Best way to enjoy a PS5 Slim Digital for 2–3 months without spending much?

I borrowed a PS5 Slim Digital Edition from a friend for around 2–3 months. It doesn't have any games installed, and I don't want to spend a lot buying games that I'll only play for a short period.

My main interests are:

**EA Sports FC (FIFA)

**Cricket games (Cricket 24 or any other good cricket game)

What would be the most cost-effective option?

-- PS Plus Extra or Deluxe?

-- Renting a PSN account (if that's safe/allowed)?

-- Buying used digital accounts?

-- Any other better option?

I also have another question. My home internet has a monthly data limit (about 1000 GB shared by the whole house).

If I play EA Sports FC or cricket games online, how much internet data do they typically use per hour? Can these games also be played completely offline after downloading and installing them?

I'd appreciate recommendations from people who have been in a similar situation.
