Welcome back.
Scroll through the F2P and Vet Armory Threads found in the 20's section. Lots of toons to check out and get ideas for gearing.
They are stickied so at the top of the threads list.
Once you know what you wanna go, or which classes, feel free to ask questions, lots of people able to assist.
If you already have a geared legion toon or have access to a 2nd account with a 120 to get into lfg transmog raids with your 110 and don’t mind gearing, you can play the 110 bracket xpon on a legion (base game) capped account too.
