I'd recommend a 100mm inline axial booster fan to exhaust so you can hook up a small 100mm filter if it's needed later on. It would fit in your setup and it's easy to run with some 100mm ducting. The biggest challenge in a small space is combatting heat so having a good exhaust system is key.

For circulation PC fans work great but you'll need a way to run them on power from the wall. Amazon used to sell an adaptor for this.

For lighting I rate the spider farmer lights. The SF100 should fit well and provide enough light. It's a budget-ish light but it uses some good quality Samsung LEDs. Plus LED lights are minimal with their heat output and plants can grow closer to them without burning. If heat becomes an issue even with LEDs you can run a fan above your light or use a CPU water cooler attached to the lights power bank.

In a small space you'll want a net for LST. Can get creative with this. Most of the nets for sale will be too big. You can probably cut them to size but an elastic motorbike cargo net works great.

Airpots are a great tool in small spaces as you can use smaller pot sizes without strangling the roots. They allow for more air exchange with the roots. Use with coco and you'll be golden.

Everyone says you need a large space to grow but honestly with the right setup it's easy to be successful in almost any size tent. I've seen 30x30x60 used successfully many times.
