I need an SMT pushbutton on my PCB. I'm drowning in options on Mouser and just want to select something that is future-proof. Is there a standard size and footprint for pushbuttons that I can use to avoid shooting myself in the foot?

This question appears to be off-topic. The users who voted to close gave this specific reason:

As others have mentioned, sort by what's in stock. That's usually a good indication of what lots of others are using.
Also, you may want to check out the Common Parts Library. A group of organizations got together to pick out specific parts of common components. I haven't personally ordered anything based on the list, but they do look like very common parts. Who knows how long it will last or if it will ever take off, but there appears to be a decent amount of people involved. It also looks geared toward the hobbyist. Looks like a good place to start anyway.
This is very typical button:
Name: Pushbutton Switches SPST OFF(ON) RND SMT MINI PB TACT SWITCH
It has very typical footprint available in many (if not all) programs for PCB design.
You can always look at stocks on Mouser or other supplier website to avoid buying "not typical" or "weird" product that may be not available later. Currently they have are over 10000pcs in stock.
