For me, the best wouldn’t be a choice of profile, but an assistant like in Windows, with “Previous” and “Next” buttons. All users know this system. For exemple:
Browser
* Bromite (default)
° Tor (security / privacy)
° No default browser
Next >
And next:
Mail
* K-9 (default)
° ProtonMail (security / privacy)
° No default mail app
< Previous Next >
Maybe add a color code to identify default and privacy options.
