Nice idea.

Sit down dinners for eight? Well, you will certainly be hanging your capacious cookware from that potrack! The dimensions of the room don't allow for a dining table the size needed for eight people to be up all the time, but there are a few ways around that. One is a console table that when folded has a small silhouette and functions as a sofa table that you put behind the sofa table to hold a lamp, your remotes, a drink, etc. When you need it, it expands, and expands, and expands! With that you can use collapsible folding chairs and there are some very nice ones, including wood ones that you can store under your bed, along with the very long tablecloths. In fact, there is an article about just that sort of table on Houzz. Then you may or may decide to not get a small table for two or as you initially thought, just get two bar stools.

To seat 8 people, tables of these configurations should be of these dimensions: Round: 60 - 66 " diameter Rectangle: 8 feet long

I need to understand the issue of the budget you are working with and what you need in your office. IMO those shelves in that space are just not good at all so I would remove those to start put your crafring stuff in a claset not the DR then If you have liked your desk facing a window why not just leave it there and IMO ther eis not enough space for both these functions so either store the dining set until you get a bigger space or use the dining table for a desk put the chirs awy and get a nice buffet for all the office stuff staired out od sight then all you need to do is out the lap top away when you want to have dinner guests I have that size DR and there is no way I could put a desk like you plan and keep my table

Is your desk a heavy duty piece with drawers etc? If not, maybe put it on casters/dollies and make it a multi-use piece (https://www.lowes.com/pd/WEN/5013732287). Could it replace your kitchen island (can't tell if that's built-in)? Then your desk can be a prep surface in the kitchen, swing around to be a small dining table, and fit against the window/wall as a buffet/bar. Mount the TV on the wall or get a sturdy display stand with a smaller footprint (like this https://www.wayfair.com/furniture/pdp/fitueyes-corner-tv-stand-for-tvs-up-to-65-ftys1863.html). Then you can tuck a bench or 2 small seats underneath it to pull out for dinners.
