Looking for suggestions for the top of this desk

Hi all :)

Apologies, I know this isn't a woodworking question, but I don't know of a better place to ask about restoring a desk like this.

It's an oak desk, but it looks like there used to be a felt inlay, or maybe vinyl. The top of the desk has an inlay of plywood, with a small raised edge to the oak, of maybe 2 - 3mm. Staining or varnishing doesn't seem to be an option, as the style of the plywood doesn't match the rest of the desk, so I'm looking for ideas for the top.

Felt or vinyl would be the obvious options, but I'm hoping to hear some other ideas. It's going to be used as an office desk, with two computer monitors and a keyboard and mouse, but also for writing, mostly notes rather than anything serious.

The underside of the plywood has oak planks running from front to back, so there's the option of removing the plywood and putting in another piece of wood, but I don't want to spend too much if I can help it.

Does anyone have any suggestions or feedback please?

Thanks in advance :)

EDIT: Sorry if I'm a bit slow to reply tonight, I'm having a mad dash to tidy up and make room for the new desk. I've managed to plan everything backwards (again...)

Note for myself - the lip is 1mm and the plywood is 3mm, as best as I can tell without dismantling anything
