I’d like to have a tool to break down my free time in a week and try to get some schedule going on, while also keeping track of upcoming events (import from google calendar would be nice). Ideally no cloud service - would like to have it offline on my PC, and would be nice if it can run in the background and play alerts/notifications for upcoming events.
Are there any tools like this that you can recommend for this? Just trying to get my weeks a bit more structured and doing it in a excel grid, while practical at first, gets tedious fast and has a lot of manual labor involved.
Personally I use Nextcloud, but as you want local only, I have used Thunderbird. It's fine. Cross platform, open source, remote to local sync. Basically, it ticks all the boxes for a calendar/agenda.

Honestly all these "Good FOSS for X" posts can be boiled down to "here check out the community awesome list of that software domain".
