Just to throw in my 2 cents and share what I did.. Hopefully you can get some ideas from it. I ran about 6000 feet of CAT 6 in my new house build a few years back. Everything is home run from area down to my utility room and the into a full rack with gear. I have rock solid ethernet anywhere it is, about 50 drops so far. (Much less in actual daily use). Can't complain and totally worth it if you're able to cable it easily (like you are with a new construction).
For plates and jacks you'll want keystones. I even use keystones for the patch panel. It sucks being stuck on certain endpoints for wiring, especially in a homelab type environment where you sometimes change your mind on stuff and upgrade over the years.
My standard package was to run 1 or more single gang boxes to each room containing 4x wires and use a single gang 4 hole keystone plate. 2x CAT 6 for ethernet, 1x CAT 5e for phone, 1x RG6 for cable TV. Later on you could also use the CAT 5e for ethernet if needed/desired. For media areas like the living room I did a double gang box for 4x CAT 6, as well as extra stuff for HDMI, etc, plus a couple CAT 6 to behind the TV. For normal bedrooms I only did one well placed drop. It's a decent sized 5 bedroom house, but lets face it, bedrooms aren't huge and the need for data there isn't huge. So far, no issues and I've been using the one room as my office with a small switch (couple PCs, couple printers, few test devices). So long as there is TV and eventually network for a computer, my wife and kids are happy. In reality the good wifi is used far more often. I did run a conduit down into the opposite bedroom walls at gang box height up into the attic (2 story house) so that if I needed to I could fish wires from my attic into the rooms and into an old work box as needed. I love conduit, run it anywhere that makes sense! For my master I did run 2x sets of gang boxes since it's a sizable room and there was more than one place I'd consider sticking a TV. I do kinda wish I ran some CAT 6 to over by where my nightstand is so that I could jack in while laying in bed on my laptop, but ohh well..
One smart thing I did was run 12 CAT6 drops from basement utility room to attic. I also ran from attic to several places outside for POE IP cams, 9 in place now, and a Unifi AP AC Pro in the attic. In my basement I'm putting in conduit between my office and utility room and such so I can futureproof those areas that I'll want faster/more later. Add as much conduit to different places as you're able.
I did get stuck for a little bit with over-analysing paralysis on the wiring, then decided simpler is better. I don't think you need to go crazy.. I mean I didn't run anything into my kitchen or laundry or bathrooms or dining room, etc. My master bath is about 180sq/ft and I considered it, but I got to thinking, wtf would I really need wiring in there for? Wall mounted TV or 40G data transfers during my morning poop? Paleezzzze! Basically all the bedrooms, the den, the family room, garage (I do use part of the garage for business). I'm working on finishing my basement now and will have several area of drops in my new office down there (including fiber from the rack), a couple runs in the gameroom side and enough stuff for my media area. My future detached garage shop will get a fiber feed and it's own wiring/VOIP/IP cam stuff, but that's down the road.
Overall I'm pretty happy with what I did and not regretting too much here..
I didn't run any fiber or anything advanced while I had the chance of only having stud walls. I didn't run CAT 6 to my doorbell for something fancy POE there. Small potatoes.
Now onto the wiring.. Sadly a bunch of my CAT 6 wiring wasn't quality. I bought a couple thousand feet online, but after that it was impromptu trips to Lowes for whatever-Lowes-had boxes that didn't have a spline in it, so it's 'maybe' CAT 6 but not quite to spec. So far in the few rooms I've tested it 10G over copper has worked just fine! That's on a 60-100ish foot run, which I'm more than happy with. Most of my runs are aroud there, the attic is maybe 120ish. Personally I'd suggest you just put in quality CAT 6 and call it a day. I don't think I'd value 6A or 7+ in a home environment. The potential noise and interference isn't there and neither are the excessive long runs. If you look at the data, the fancier cables mostly just handle higher speeds at longer distances and such. Is that part of your design specs? The other thing is the difficulty in terminating the fancier cable (can you even do it correctly to spec? At what cost? Shielding/grounding?). It just seems like too much of a hassle for not enough benefit. Plus the fancier connector can cost a bundle more. 2x 3x the price sometimes for the same thing. Lots of 75ish cent CAT 6 keystones online and they always pass my Klein LAN tester and my speed of file transfer seat of the pants tests. I'm happy with that. I'd have no qualms with buying boxes of solid core wire from Monoprice and calling it a day. That's what I'm doing in my basement, with a fiber feed for the fast workstation to server link.
Good luck!
