Prepaid SIMs in Germany / Prepaid Jahrestarif

I need a German phone number, so I need a German SIM.

My preference would be a prepaid year because it’s a bit cheaper. Also, I have a physical sim slot and would rather use a physical sim than an eSIM.

Many apps (Mein O2, MeinMagenta for cell services and most of the local transit apps) are region locked. I can’t currently change my Apple ID to Germany and can’t make a new Apple ID for Germany without a German phone number.

Any hot takes on Telekom, Vodafone, O2, etc. or recommendations on getting a physical SIM card?

Note: The Aldi closest to me only had eSIM today or thought they only had eSIM.

Edit: I actually need a phone number for things, e.g. kita being able to call me if one of my kids get sick at daycare.
