My group has been using owlbear rodeo. The current DM makes a lot of maps and uses owlbear’s fog of war tool to reveal as we explore. It’s fine.
I used it once just sketching the map as we went using it’s drawing tools. Also fine. Like a dry erase board, but more awkward because of using a mouse instead of a marker.
In person I had a dry erase board with a grid printed on it, a bunch of tokens from board games, and coins to use as stuff.
I also used Google sheets for a while during the pandemic. It gives you a grid you can color and mark and everyone can see and edit. Worked surprisingly well. Also good for note taking
