Minimal equipment home gym

Hey! I have a question (duh). 35yo here, getting back at the gym (home gym i must say) after been unabled to run (thank you, Achilles tendinitis). I was training when i was younger, i stopped and now I got some motivation back, i need to surf on that wave.

I bought a half squat rack so I can do some exercises with the olympic bar. It wasnt in my intentions to buy dumbbells because of the lack of space and money mostly. I do have resistance bands (and handles and a rope to attach), but alongside a pull up bar and a landmine attachment too, that's it.

I dont have big goals. I want to build muscle, but mostly to be stronger and prevent injuries in the long run. When I will get back at running, I will probably try an Hyrox Event.

So, introduction done, is my equipment enough for my goals ? I am considering buying a cheap double pulley system that would allow me to do more exercises, but not quite sure if it is worth it. What would you add?

What do you think ? Thank you!

(Sorry, english is not my first langage)
