A good PWA is almost indistinguishable from a native app.
On Android, where they've bothered to implement the apis for it you've got access to all the same stuff (camera, location, Bluetooth etc)
Apple has less, which is ironic because originally the iOS platform was only going to be PWAs. I guess discovering they could take a 30% cut of all money taken changed their mind.
I recommend you take a look at https://elk.zone as an example of an excellent PWA (be sure to actually install it and use it that way)
