My solution was pairing it with the controller on Switch mode.

[Hybrid]

Linux Mint 22.1.
Kernel 6.11.0.21
Full disclosure, I'm a Linux noob.
Just in case someone searches the internet having the same issue.

Just got the 8bitdo pro 2 Hall effect version.
Could connect via bluetooth but it went on a circle of connecting and disconnecting. When I menaged to keep it connected It didn't show up on Steam and didn't work. With USB cable it worked instantly.
What worked for me:
0. Set controller to X mode (like for PC windows)
1. Write down or better copy the MAC address of the controller sth. like E4:XX:XX:XX:XX:XX
2. Remove the controller from blueman app.
3. Close blueman app
4. Open terminal and use the command -> bluetoothctl
5. turn on controller,set it to pairing mode and use the terminalcommand -> scan on
6. use command trust <MAC address> (for example: trust E4:XX:XX:XX:XX:XX)
7. use command pair <MAC address>
8. use command connect <MAC adress>
9. After the controller is shown as detected in the terminal you can use command -> scan off
I just left it on until I was done and had no issues.

After that it worked even after the restart. Could turn controller on and off without issues. It even worked after I opened the blueman app again. It even showed up in the blueman app.
As far as I can tell from reading others experiences this specific issue could have to do with the order of how the gamepad connects AND seem to be an issue with the blueman app as of the date of writing. So the order: trust-pair-connect worked for me.
Hopefully this will help someone someday.

What got me to the solution was this github:
