So, I am considering using epoxy...
What kind(s)? Brands/variety, etc.
I can go to the local hardware stores but they typically do not have much variety in their stock, other than common latex house paints and such.
I don't have a brand to recommend but I did find a link with some info: https://woodimprove.com/best-epoxy-resins-for-wood/
You would be looking for one of two kinds, either a tabletop type or a spray type. The spray type will give a more uniform and possibly smoother finish but it can be tricky to spray and you may be kissing the spray gun goodbye in the process. The tabletop type has to be thin enough to brush or preferably roll on and it has to set slow enough that it has time to self level. The advantage of epoxy is that it will probably be easy to touch up if necessary. The main downside is the cost. Fumes and the trickiness could also be too.
Another option is counter top laminate. The laminate is easy to put on, cheaper than epoxy, and will be really easy to clean up. However, it can scratch and chip (if you pound on it or drop some heavy and pointy on it) and you'd have to replace it instead repairing it. You wouldn't need a full sheet and the leftover is handy for other things. I use a lot of it for drawer glides for example. A strip of it on your carcass and another on the bottom edges of the drawer are almost as good as roller slides.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
