I added coolant. If just thermostat is stuck, would it be wise to first get it replaced? Can a mechanic tell if it is stuck?

We should do two things to check this. First we need pressure test the system to make sure there are no leaks. Here is a guide that will show how to do this.

The next thing we need to do is use a laser temp gauge to find out if we have higher temp before the thermostat then after. If you do then the thermostat is stuck closed and it does need to be replaced.

I would not let this go because the engine is going to continue to overheat and eventually it will cause a head gasket issue or worse.
So let us know what you find with this and we can go from there. Thanks
