do these work on the thumb?

It depends on how long your thumb is I have really short fat fingers and had to return these and make my own splint

how do I know what size to get, I see no guidance for this.

There is a pdf file link in the full product description. It asks you to print out a sizing band at default printer settings. However, using a new Brother printer, it printed out 1/16 of an inch too small, and I had to bump it up to 103% to make it match the 3½" marker on the printout.

Are these very rigid or semi-flexible? Could I type while wearing it?

They are Rigid n strong. I use one on my pinky n one on my thumb and I type all day on & off with these. I have RA and when my fingers are swollen n stuff, to bend them gives me extreme pain !! So I bought these splints to prevent my fingers from bending you can take them off, move them around. Also another note: I have bigger sizes, there’s one where it comes w/ 32 sizes on a big round keychain. When my fingers r swollen or if ur finger is Broke, you will go they several different sizes. So getting the 3 pack in ur size is perfectly fine, but you may need a few in the sizes before & after I hope this helps !! Good Luck !!
