I also did a physics undergrad (in person) and can attest that most of the classes these days are theory-based. Lots of maths; Quantum Mechanics is all maths, Nuclear/Particle is all theoretical/computational (though at the point of masters/PhD you would get to fire lasers at real things, I never did though). I did have one experimental lab class where we practiced measurements of various sorts, but that was maybe 10-20% of the first couple years. You could take different electives that emphasize experimental physics more, but the theory is plenty deep to keep you busy without compromising. So if you want to learn quantum physics or stellar nuclear physics for example you don’t need a lab at all.
