Pixelmator is great and integrates well with Apple's tooling for batch processing.

For video, the free version of DavinciResolve goes a very long way, and their Studio is a single-payment-life-time license.

DaVinci Resolve also runs on Linux, so you won't be locked to staying on MacOS if you want to switch OSes but maintain your skillset.
