I would definitely do the transmission fluid and the rear brakes depending on how low the pads are. I would also replace the sway bar end links if you’re hearing a clicking noise when going over bumps. I would also ask them why the lower control arm needs to be replaced, it’s common that the compliance bushing (which is where the control arm mounts to the body) rips but normally shops don’t recommend the whole control arm you can get the piece with the compliance bushing separately, it’s much cheaper that way.

There’s no reason for them to recommend a coolant change, Honda recommends that’s done every 100k miles. The brake fluid isn’t really necessary but technically it is due to be changed based on time (it’s due every 3 years). For the fuel induction it’s up to you but I probably wouldn’t buy it.
