Adding to what others here have already said, I’d definitely download Signal and see if you can get any people to move from WhatsApp/Telegram/whatever to Signal.
I don’t know much about iOS apps, but you could look into more privacy focused YouTube clients, and possibly 2FA clients too (although that’s a bit of a controversial topic on iOS AFAIK).
I saw you mention in another comment that you use Amazon Alexa for smart home appliances. Depending on interest in selfhosting / time / motivation to move away from Amazon, you could look into using Home Assistant instead. It even has a Lemmy community: [email protected].
My personal gripe with mobile Firefox is searching by using the address bar.
I have had countless times where I put in my search prompt, followed by pressing the little X all the way on the right and thus clearing the address bar. My brain just really expects an enter button to be there.
I think my current record is entering a search term and then clearing it literally directly 3 times in a row, getting more and more confused each time.
