https://gitlab.com/corectrl/corectrl should do it. I've got a 6900XT and undervolting works fine. So does core clock and fan curve, but memory clock has issues: https://gitlab.com/corectrl/corectrl/-/issues/139 (edit: that issue is closed, so maybe it works now).

As far as peripherals, sometimes it works better than windows and sometimes not great. I'd look up the specific wheel you plan to buy and see if it's supported or someone has built something to support it. For example, you've got piper (https://github.com/libratbag/piper) for Logitech devices.
