Depending on how the glue looks, floating floor may be a good option - inexpensive, easy to install and relatively easy uninstall, hides minor deviations in the subfloor (uneveness, glue and other stuck items) so you are walking on a smooth surface. Also easier to clean than carpet (spills and what not).

I am not sure what the carpet is that @cbg mentioned, there are indoor/outdoor options that are easy to lay down and tape as mentioned but there may be some bumps in the floor if the glue from the carpet tile doesn’t all come off. There is a version of indoor carpet with attached padding that will hide some of that glue and you can use tape in the doorways and high traffic areas.
Regular indoor carpeting doesn’t always work well with just tape since the backing isn’t smooth.
I wouldn’t suggest sheet vinyl since it will curl if not properly secured and properly securing is probably more work than it’s worth.
Self stick vinyl tile may be an option but plywood is relatively porous so self stick adhesive on the tile doesn’t always stick well.
My vote is plank flooring…but I also tend to prefer hard surfaces…so…
