I’ll define subscription services as any of the various streaming video or audio services, video games, print publications, any of the many “crates” (collectibles, razors, food, clothing). I’ve probably left some out but basically reoccurring monthly payments that are not mortgage/rent, utilities, cables, etc.
Mommypants and I normally have three.

I’ve considered Acorn, but I don’t watch a ton of tv, so why add something that will increase my tv time?
Oops, that reminds me – I forgot to list my Sirius subscription.

Sunset magazine
AARP magazine

There are probably others I can’t think of.

Very few are monthly. Usually I prepay a year, like all of my wife’s magazines and most of my business services (things like DropBox and Office 365 Exchange)
On the personal side, I think NetFlix is the only monthly non-insurance non-utility item.
I’m glad this thread was started. I realized that I haven’t used Ancestry for quite some time and cancelled my subscription.
