Hi and welcome back to knitting and to the forum!
I take a low tech approach and use sticky notes to mark my place in a pattern. I like a copy of the pattern that I feel free to mark up or write on the back of. And I find it especially helpful for Aran patterns or multiple cable patterns, to mark the different stitch combinations in different color highlighter. It just makes it easier to see a glance which stitches I should be using.
