basement subpanel suggestions/advice desired

1 year 3200 sq/ft home plus 1500 sq/ft unfinished basement
CL 200 meter.

BR2040B200 Panel in garage (pretty much full)
3@ 15amp ARC circuit breaker
3@ 15/15 amp tandem circuit breaker
2@ 15amp circuit breaker
6@ 20 amp circuit breaker
2@ 220v 40 amp circuit breaker (AC&Range)
1@ 220v 30 amp circuit breaker (Dryer)

Basement is framed and has 1 outlet & 1 light per room (bought that way)

We will later be adding addditional HVAC unit for basement - uncertain if gas/electic. Basement will end up with 2 bedrooms and 1 bathroom, as well as 2 large rooms - probably one as a game room, pool table/etc, and the other possibly as a home theatre room with projector. We may also put in a small wet bar.

Today, we are considering small wood shop in basement as well. We would likely eliminate this prior to selling home. We also may need some power for outdoor living space - limited lighting, electric - nothign spectacular. Possible light and an outlet or two in small storage shed, close to home.

Need more breaker space, regardless of path. Everything in basement is exposed. Cutting out sheetrock in garage is no big deal.

Do we
a) replace existing panel with another 200amp panel with more spaces?
b) add another of same panel next to existing?
c) add another 200amp panel with more spaces and move existing panel to basement?

If you need more info, let me know. What would you recommend? Cost-wise? Convenience-wise? Any [dis]advantages to having the subpanel in basement over garage? Is there any value/appeal to potential buyers for one method over another? Your comments and feedback are very much appreciated. Thanks.

Most 200a panels have room for 40-44 circuits
Best to have the bigger panel as your main panel

So put in a new bigger 200a
Then instead of buying a sub-panel use the old 200a as a sub
Feed it with 100a-150a depending upon needs/ load calc for house

I'd go with A and tell the clown who installed it that he's an idiot for installing a 20 space panel.

You do have a big ass house and the 3rd AC is one rule of thumb for an upgrade over 200A.

It will of course cost thousands more to upgrade than to simply install a full sized panel.
