DSLR Mirrorless - Lens suggestions

I recently acquired a Sony a6000 to start up a few short videos/films. The provided lens is decent but a zoom lens, and lack the beauty of some of the primes I got used to working with a friend.
After hunting around a few websites I am a little unsure of what lenses I should aim for. Any suggestions?

You are looking for high quality lenses that can be adapted to a variety of cameras, including the one you have. The PL mount is pretty ubiquitous for high end cameras and can be adapted to most others. This allows you to use the lenses in the widest range of situations. Lenses are a long term investment, think decades of use, so buy accordingly.

Indeed, it has been stressing me a bit. Been staring at various prime lenses forever - also rental places.
Thanks for pointing that out on the PL lenses and adapters. I hear Metabones adapters are pretty good.

Going to an APS-C sized sensor a PL mount lens should not need any optical correction. The simplest adapter would just securely mount onto the camera and provide a stable rigid mount for the PL lens 52mm from the sensor. While I've seen Metabones products, I've never personally used them so cannot comment.

If you plan on manual focusing, you can get an adapter and go for some vintage full frame still lenses like canon FD lenses. The crop factor will be a bit different so the lenses will shoot longer (look more zoomed in). But you can get some real great lenses for cheap to play around with that way.

Be aware that some mounts (PL for instance) may be too deep and hit your sensor.
