I don't know of 3rd party calendar apps - the flow I've always used has been
With that in mind, the two apps that I've used are CalDAV-Sync and DAVx^(5). Neither is free, but have both always been super reliable for me syncing with both radicale and owncloud|nextcloud backends. Currently using DAVx^(5) just because it also bundles in contact and task syncing, and I like having fewer things running on my phone.
Take a look at CalDAV-Sync: https://play.google.com/store/apps/details?id=org.dmfs.caldav.lib
This is not a recommendation, this app has issues but it may work for you in your case. Or it may not. :)
I think that's up to TickTick? Calendar storage syncs with Google Calendar more often than that.
You can look into setting up your own calendars using something like CalDav-sync, which can sync with a wide variety of services that aren't Google (the developer also has apps that can sync with iCalendar, and apps that can sync contacts).
Using that app you can sync calendar and contact storage with those external calendars and contacts, and even self-host them. But the contacts/calendar apps you use need to be able to show them.
In the description for TickTick I see that it claims to be able to integrate with more than just Google Calendar so maybe you can find a type of calendar that works.
CalDAV-Sync, its like $3, and works great.

I use FastMail to de-Google myself and sync it to my Android phone's calendar using (CalDAV-Sync)[https://play.google.com/store/apps/details?id=org.dmfs.caldav.lib].
I think FastMail is used by a lot of people that do not want to use Google for everything.
Also I would love it to look more like the linked watch faces, so not just the small border of a circle but more of a (flat) pie chartish kinda look.
I use CalDAV-Sync on my smartphone and Bynari WebDAV Collaborator with outlook. Both tools work ok, but not flawless.
I am slowly moving away from Microsoft and Google.
So I started using Thunderbird for contacts, calendar and also to fetch my email from my domain hosting.
I set Thunderbird to use an Owncloud service. €5 per year gets plenty of space. I chose Open IT Store basically at random.
On Android you set up CalDav and CardDav and point them at the same place on Owncloud. Then I use Simple Contacts and Simple Calendar to see what I need to see.
I'll admit, it was all a little fiddly to set up, but there are tutorials out there to help get it together. Most of the work on the phone needs to be done under Setting/ Account. You might also see duplicate contacts. Look for Filter on Simple Calendar.
I eventually upgraded to a much bigger Owncloud account, and got rid of Dropbox. There is a very decent Android app for it as well.
Looks like it's using an xml markup:

I've settled on using todoman + Baïkal for CLI-based todo management, and adding CalDAV-Sync + OpenTasks on Android.
I was a much bigger fan of task warrior. But I haven't gotten around to tackling taskd yet, while I already installed Baïkal for Calendar/Contacts.
There are a number of good alternatives listed here already, but thought I'd share this one.
I went through the process of switching from Gmail in early 2019, and eventually settled on Fastmail on their Standard plan.
Grab a drink, here's some information:
@fastmail.com
. You can also set up a number of aliases that can use the same or a different domain choice.username+<text>@domain
email format and supports <text>@username.domain
for sites and email servers that were built without reading the SMTP RFCs.I have no connection with them, beyond being a customer.
tl;dr: If you'd told me 5+ years ago that I'd soon be voluntarily paying for email I'd have laughed in your face. Now I'm more than happy paying US$60+VAT per year and advocate for doing so.

Same guy who created opentasks. Works out of the box with his caldav-adapter, but not with Davdroid...
I use this instead.
I ran into this problem too only some things would sync, I already owned cal-davsync so used that with no problems

FYI, RFC4791 and RFC5545 both codify "to-dos" (VTODO) as a standard object type in the CalDAV and iCalendar standards. It's used by several products on multiple platforms (though Google sadly omits support in its own API). I use Evolution under Ubuntu, and CalDAV-Sync and OpenTasks on Android (the latter app has java source code available). Both talk to Darwin CalendarServer on a Debian box.
