I’ve been thinking this is the best reset button, the only thing I don’t like is that it sticks out on the bottom of the PCB too, wish it wasn’t as tall…
Yes, those are fine for a side push reset button. Based on the original Alps one (which aren’t that expensive either https://lcsc.com/product-detail/Tactile-Switches_ALPS-Electric-SKSCLDE010_C115362.html). I’m sure you could find cheaper versions in the same form factor on lcsc.com, should you want a slightly more repeatable part source (lcsc does seem, when an item is listed as out of stock, to be arbitrary about what they are planning to restock and what they’re leaving on the website but not intending to restock).

Here’s an example of something that comes to around $0.02 in qty 1k and isn’t much more for qty 10. The footprint from glancing at a couple of similar buttons is pretty standard (not the same as the Alps ones above) so it might not matter if the China brand you started with goes out of stock, especially on a reset button where the feel doesn’t need to be consistent.
