Use solid wire in the wall. It performs better. Use stranded wire for patch cords where you need flexibility.
Where is a good place to buy the keystones and wall plates?
Monoprice, local local big box home improvement store, lots of other places...
Is cat6 enough for everything, or do I need to pull HDMI?
Depends on what you want. Most folks run coax as well. HDMI may be appropriate in some locations. Check out the numerous threads in these forums on the topic.
Is there any value in pulling fiber?
Probably not unless you have really long runs. You can do HDMI over Cat 6 up to 100m with HDBaseT, longer than that if you daisy chain.
What kind of speaker wire should I get? Is stranded or solid better for speaker cable? Should I get the 2 conductor wrapped in insulation, or the one with 2 conductors separately wrapped in insulation with a jacket over the top? Monoprice had both and the latter is cheaper by a few cents.
There is no difference in performance between stranded and solid speaker wire. Stranded is usually used because it is easier to work with. Architectural wire (the kind that goes in walls) is normally sheathed to protect the wires during installation and after. Wire that is going in walls, ceilings, etc. needs to be appropriately listed (CL2, CL3, or CM).
...do I just leave bare speaker wire in the joists about where I plan to put the speaker (assuming speaker goes in after drywall)?
Yes. Make sure it isn't in the way of the trades who are working on your house. Take lots of pictures before the drywall goes up so you can find everything.
