m4 or m5 air

Guys, I'm in a bit of a dillema.

Getting my first macbook in a couple of weeks and can't decide between:

M4 Air 24/512 - 1050€

M5 Air 24/1TB - 1500€

I edit video and design motion graphics as a freelancer (99% of the work is 2D), but I'm still at the start of my journey and can't afford a pro at this point. I'm currently editing on a 2022 Strix G15 with a ryzen 7 and a 3070ti, but the UI lag in Adobe apps on windows is making it almost unusable. I'm aware that both of those machines are moreso sidegrades/small upgrades, but I just need something that will allow me to work without crashing and completely stopping when it throttles/hits ram limits.

I am aware that the m5 has a beefier GPU which would be great for After Effects, but I don't know if its 500€ better.

I also already own a Samsung T7 2TB so the 512 internal SSD would work, although the 1tb seems way nicer

I've also seen reviews that say that the m5 throttles much earlier than the m4, resulting in slower exports in real world tests (reviews are mixed on this, some people say its slower, some say its faster).

No, desktops are not an option.

EU has really shit resell prices, The cheapest pro in this pricerange is an m1 pro/max, but I don't want to get those because of lack of support in upcomming years since the laptop will be given out to a family member after I upgrade eventually.

Apple refurbished isn't availible in my area.
