I don't know what this 'gallium' is. But your computer has a powerful x86 cpu, so any regular distro will work just fine.
Becuse it is your first distro, it should be something well documented (large user base) and stable.
I recommend you to format your biggest usb stick with Ventoy2Disk and it'll be the last time you'll ever format.
With Ventoy you can try any distro in Live mode without installing anything in your computer before you're found your favorite.
Try at least Pop_OS! and LMDE5 (LMDE6 is released within a few weeks) over regular Mint and here's why: https://forums.linuxmint.com/viewtopic.php?t=374128
