I have been using my Nano X for a couple of months now, and I have installed multiple apps, just because of wanting to try the capacity. I did not encounter problems when installing the most popular coins. I have arrived up to 10 apps, still no difficulty. I remembered using my Nano S and had reached the limit of the capacity when I installed around four apps if IIRC.

I would still recommend Nano X for everyday use. It's not just the capacity that you should consider.  The portability and the capability of managing apps right in your phone if you need it, it's easy. No OTG cable required, as long as you have a smartphone. I'm not worried about Bluetooth hacking or something, it's not turned on for a long time and it's just a few minutes when it is turned on.
