Maybe it's different in the U.S. still, but where I live in Canada lately it seems like everyone is on Signal
Oh really? I am curious how Signal won with WhatsApp.
In France (and basically in all European countries, maybe except Germany, where all privacy things are very intense so maybe they use something else), WhatsApp is the go-to app.
Not only do most people use it, but you have services that suggest WhatsApp as one of the contact channels. This is not because they love WhatsApp for some reason - rather because people use it (and they want to make it easier to contact them).
You talk about "WhatsApp groups for X", never heard about "Signal groups for X". In rare instances, this would be Telegram (but usually specialized groups)

Probably because people are just about completely done with Facebook/Meta.
Signal is seen as the best option for privacy.
People will call the bad guys "hackers" (should be crackers!), in French they will say "show me the digits" when they mean "numbers" and so on.
If everyone uses Whatsapp then you will be alone with these apps nobody heard about. You can try to evangelize them but their friends use WhatsApp.
It's a choice between hard core values and keeping in touch.
