Passenger front rotor/wheel hot. Stuck caliper?

2004 Toyota Prius. I noticed after a 5 mile drive the front passenger tire and rotor was hot. Almost enough to burn. I could feel the heat radiating from the tire. Driver's side tire felt cool to the touch.

Recently, after not driving for the car for a week and after rain, the car seemed "stuck" and required a little gas to get moving while on flat ground.

The car can't really move while in drive with no gas applied on flat ground. I think it's because of the right front tire.

No noises, did front wheel bearings a year ago. Front pads and rotors 3 years ago. Calipers are at least 7 years old but probably original.

Jacked the car up on the front. Could rotate the driver's side tire but not the passenger while in neutral.

Should I just replace the calipers? I am getting a tool to compress the pistons and will check to see if the slide pins can move. I am thinking I should test to see if the caliper pistons can be pushed inward.

Thank you
