Using 3D camera move problem...cannot keep motion smooth between multiple camera keyframes...

So i want to do a camera pan over a 3d set with the camera rotating and turning and such…maybe with 3-4 keyframes but every middle camera fram, say, 2nd, 3rd, if i rotate the camera or adjust it the momvemt isnt smooth…and/or it’ll speed up/slow down even if theres no ease in/out added to the frame. I know theres the tension continuity bias but you have ZERO tutorials on that. Or does such a tutorial exist that shows how to do smooth samera moves over and around 3D sets/objects?

I also went into the function editor to attempt to pull out bezier handles but it doesnt seem like you can do that n camera keyframes…only use ease in out stuff. What am I missing here?
