Next camera after Sony zv1?

Hello I’m about to graduate as a marketing degree. I usually film with my iPhone, zv1 and pocket 3. I’m looking for an upgrade for my zv1 to a full frame. I’m still somewhat new to cinematography and I just want to experience the full frame camera for future projects as well as personal use.

Anyone here have tips on what camera they would suggest for me to look into to get?

Currently the dream camera is FX3 but I’m looking into getting Sony a7sii since it’s cheap but I also found out that it only has 30min recording time. Anyone has any suggestions or advice for me?

Thank you all in advance!
