My 2c:

If you're new to Linux, you're on a run of the mill desktop/laptop, and are used to Windows use Linux Mint.

If you're new to Linux, you're not primarily a Windows user or you have non standard hardware (e.g. x86_64 tablet/2in1), then use Ubuntu.

If youre new to Linux, have Nvidia & intend to game, and feel uncomfortable manually installing drivers use the PopOS version with the Nvidia drivers integrated.

If you have been on Linux for a bit and feel comfortable then use Debian. It's stable, will do just about anything you need, and flatpacks/snaps/appimages can solve any need for the latest packege. You can always switch to the testing repos as well for a faster upgrade schedule (or sid for  near rolling release scheduled).

If you have been on Linux for a while - have the know how and time for maintaining it - and a specific need or desire to have everything on your be on a rolling release, use Arch.
