Hello STH community how are you doing? I brought last Sept, 4TB elements drives which turned out are all WD40EMAZ, finding out these are all SMR drives and I've currently got them in a raid-z1 array.

With a drive failure and the rebuild times are quite long I was wondering sort of what would my options be on these encase I get one that failed. Unfortunately I don't think I can just replace these for something like IronWolf drives due to funds all at once.

Going forward would freenas be okay with the SMR drives or should I look into another solution say windows storage spaces or unraid?

Do not under any circumstance use SMR drives for ZFS. They are fine stand alone in a workstation. These are not NAS, RAID, or ZFS compliant.

I am going to replace these for CMR drives, however at the minute these are the only SMR drives I have in there.

SMR drives are simply much slower than CMR (besides the IDNF issue). An SMR drive may work in other RAID technology, however they can be 5x slower than a CMR. If you absolutely want 4TB you can look at ironwolf. Otherwise WD Easystore 12TB is the sweet spot right now.
