I would like to have a central Calendar that I could sync everything to it, from my email calendars and my to do list, is there something like that selfhosted or not, that is FOSS?

Then, maybe, Baikal a Cal-/ Card-DAV server is what you are searching for.
What clients would you recommend with it?
In principle any DAV client should work. On Android, I use DAVx5 and Tasks.org to access my Nextcloud. On Thunderbird + Lightning, you can e.g. use SOGo connector or TbSync to use the address books, calendars and tasks.
