Hard to say without more context. I’d check the existing distributions and pick one that suits you. Their websites usually have lists with compatible devices.
PostmarketOS is interesting for tinkering, grapheneOS just works reliably. Everything else in between
PostmarkedOS is a bit frustrating as it makes you jumping through many hoops if you want to install anything not 100% FoSS (due to alpine base)
I personally think arch and mobian are the best options right now, using the phosh UI (I like gnome-mobile as well, but it is not as mobile friendly as phosh)
Now to the hardware part, you have basically two options:
Use a phone where most drivers are in the mainline kernel, but with bad performance due to weak SoC (e.g. pine phone pro)
Use a phone with strong(er) SoC but relay on custom kernel from the phone brand, locking you in place of the version of the kernel they modified (e.g. oneplus 6, I think)
At least this is how I remember it
When we come to App support; you mostly have to rely on webApps for proprietary services like train ticket, uber, etc.
For massages, I would recommend a Matrix server and the various bridges to third party messaging services that exist for it (be aware that some services consider a connection via bridge as incompatible with their ToS and may block you)
