Okay I bought 4 but only received 3 at this time.
Just tested them all, they all work with the Pinephone Pro (maybe that shouldn't be a surprise).
I'm using an Anker Nano II 65W charger
Tested these USB-C adapters:
TOTU 9-in-1 Type C (this one is nice has card readers and ethernet)
QGeeM 4-in-1 (small)
j5create as mentioned above works (this one is big/has ethernet but does not have card readers)
I bough two different right-angle USB-C adapters for portrait docks and they both work tested with TOTU (design/feature-set I like best)
Not tested yet:
The other one I bought is an Anker 7-in-1 this one also looks nice as far as included card reader no ethernet though.
I have not received this one yet.
Update
Anker USB-C to HDMI works no surprise I guess
