This is something Android messed up since Android 9 (IIRC). You used to have a small arrow below the Wifi and Bluetooth (and whatnot) icons where you could select what to connect to. Removing those since 9 was partially what drove me to angrily expore iOS.
Can't say about the spellcheck because I used Swiftkey on iOS but the Android version is miles ahead of it. In hindsight I should've probably just reverted to the iOS built-in one.
My ideal is that I can flip up and change the source in the time it takes for a song to change, which I used to be able to do seamlessly in Android. Though according to the sibling comment, Android got worse for that use since I switched too.
Just wish both had some kind of UI indicator that there's a long-press action available... it's not like people are reading mobile phone manuals nowadays, even if they existed.

Personally I think the down arrow is way too small for me to press so I always just long press the icon anyway.
And for the love of god why does your spellcheck keep trying to replace the word "talk" with "ya'll?" I've had to manually set text replacement for way too many word pairs like that, and if you do typo the word you're going for in a way that's not in the text replacement, it defaults to the weird choice anyway.
