How many current carrying conductors can go inside a 1” EMT pipe, with 20 amp breakers? And does it make a difference if the conductors are stranded as opposed to solid?

Fair number of variables... insulation type, ambient, length etc.
But assuming THWN-2 insulation and greater than 24" you can get 16 #10s. If all were current carrying the derating would be 50% so the 90° adjustment would be 20 amps.
Solid or stranded would be the same.
