Never had an issue with caldav and cardav. Maybe you are using broken servers or clients?
Even notes can be done efficiently on those standards...
But, hey, I am using only FOSS server and clients, maybe you referring to proprietary ones? You know, those who are mare by vendors who have no interest in interoperability?
The open source market for smart watches sucks. Gadget bridge doesn't really work for any "new" (i might be wrong here) devices.
Luckly Garmin watches are top notch and the software side its pretty good. You can not install the app and manually download all activities files via USB if you like.
Crappy (30-40mbit/sec) but uncapped FTTC here, plus 5G FVA at 300mbit/sec but 1Tb monthly cap here.
Combining both and separating heavy traffic (fucking fortnite and many steam big games) on the crappy uncapoed, and arr'ing too, leaves tons of data for high speed anything.
Total cost? 22€ + 24€ = 46€/month, no surprises. A lot more expensive than having fiber indeed, but I am deep into the woods, so.
Ah, and when i go over my 1Tb data cap on the FVA, I get throttled to 6mbit/sec, nothing extra to pay.
