Honestly, Custom ROMs have been in decline of usage since few years.
There are also Other ROMS like Pixel Experience, PixyOS, Havoc, evolutionX, PixelOS, Paranoid, Derpfest, CrDroid and lot more.
The reason for the drop is due to a combination of reasons like better OEM UI, unpublished Kernel code (Chinese OEMs, Mediatek), locked bootloaders and Safetynet issues.
Do custom ROMs still have issues with some apps not allowing them? It’s been an eternity since I tried one and I don’t know if it’s a hard requirement, but at least when I did try it, I had (?) to root my device and my bank apps refused to work after that.

I’m currently rocking CrDroid it has currently ~85K active devices (https://stats.crdroid.net/).
Fun part of this is that it relies entirelly on Googles tracking framework.

I haven’t encountered such a thing yet (been using for 5 months).
There are lot of methods to bypass those checks even now, and often many ROMs do this by default. (LineageOS doesn’t do that afaik)
Some banking or payment apps can detect root and won’t let you use them.
When I used to run Custom ROMs I just used magisk to hide the root and these apps would work fine afterwards.
