You are not alone in observing that many shops have diminished stock in instruments. COVID didn't help with that but the shift in recent years towards online instrument sales also plays a role and that began before COVID was a thing. It's a shame for those of us who want to hold the instrument in hand before buying it!
I am supportive (and a wee bit envious as a parent of two young kids) of your decision to pursue a home studio as your hobby. If you are getting into this seriously I would recommend getting at least a 50W practice amp, or bigger if you plan on playing with others. 200W is typically the minimum you can get away with if you're playing with a drummer and a full kit, but something like 500W will go further. A preamp pedal is also a nice thing to have, you can use that as a DI box for recording. Look for one with an XLR output. There are a LOT of options here and if you want suggestions, that's a whole 'nother thread.
