I've been using Thunderbird's Lightning add-on for a lack of alternatives but it's mostly been a PITA.

It's not 'slick' by 2021 app standards but it does what it needs to do pretty well. And compared to some apps, it uses almost no memory.
On my phone, I combine it with FairEmail, DAVx5 and OpenTasks.
I've connected it to both Google Calendar and Nextcloud's calendar, and it works perfectly well, provides notifications, recurring events, and I can quickly access today's events just by clicking on the clock on the bar. No complaints what so ever.
elementary's tasks app, on the other hand, is still WIP.
I recently also started using it with my work-mandated Office 365 calendar. According to some docs somewhere that I can't find right now, there were quite a few hoops to jump through to make that read/write so I settled for read-only.
I don't think I will leave Firefox for it but I might just use it just for the calendar.
