Moving to a custom ROM is always a good move in my book, unfortunately it won’t solve the security update issue. Once a company (I.e. Samsung, Google, Oneplus) stops pushing security updates, custom ROMs developed for the phone pretty much stop getting them as well. You’d continue to get OS updates though, depending on the ROM developer. If security updates aren’t super important to your threat model then that’s all non-issue.
Long story short, you won’t really have any problems with app compatibility on a custom ROM. I’ve run the following OS on various devices:
LineageOS
LineageOS (with Gapps installed)
LineageOS for microg
CalyxOS
GrapheneOS
Any ROM that includes Gapps will work with streaming and banking no problem. It’ll function the same as stock android.
Graphene works with every banking and streaming app ive tried. The only two commonly used services it cannot run are Android Auto and Google Pay.
Anything that uses MicroG (CalyxOS, lineage for MicroG) also worked with all the streaming and banking apps ive tested. You may run in to more trouble running Google specific services here though. RCS wouldnt work for me in Google messages, but I think that was the only problem I ran in to personally.
In the end a custom ROM that is based on open source software is always going to be a better experience. I’d recommend checking out the Techlore youtube channel as a means for finding open source android software resources, as there are some amazing alternatives to commonly used proprietary apps.

Some banking apps won’t work if you have an open bootloader, this is why i use a separate phone for banking apps.
Ive heard that, though haven’t run in to it myself. I can confirm that Chase, Amex, BOA and Discover apps all work on the above OSs.
