My Logitech G503 Lightspeed wireless mouse works instantly on my computer. Plug and play. Running Pop!_OS.

Gaming works great in Steam and Lutris.

Can’t speak for battery and power management, but I do have a laptop with Pop installed on it as well. Haven’t had any troubles, but it’s out of commission right now due to an unrelated hard drive cable issue.

Spot on about Excel, I suppose. I’ve never much liked libreoffice or Google sheets for tables.
