is a 50cm sized pot too large for a grafted aubergine plant?

I'm ashamed to say that I have been a bit exuberant and have bought a grafted aubergine plant full price from the garden centre
My understanding is that the plants have a strong route system, so my idea was that the larger the pot the better. Even though the label says that a minimum of 30 cm will do, it seems a bit small to me. Im not putting it in the ground as planned as I've not been able to work the ground for the last 6 weeks or so and buy the time I that i get it done it will be a bit late.

Is a 50 cm pot too big for one grafted aubergine plant? How about grafted tomatoes? Any ideas?
I am planning to grow the aubergine under cover.

Not too big, always bigger the better for toms, peppers and aubs. It gives roots space to grow as they'd like, just as they do in the soil - so go for it

Thankyou, the huge 50 cm pot compared to what I normally use (free plastic black buckets) looks huge, but i'm going for it. Most of my tomatoes will be in the ground, but I want to spoil the grafted aubergine, as its not going in the ground, and maybe a single grafted tomatoe too, to compare it to those in the ground, grafted and non grafted. I just need to hurry up and get the ground ready asap.

There's no such thing as too big. Although it is probably bigger than it needs to be.
In theory, a 30cm pot would probably produce the same crop as a 50cm one. I say "in theory" because a smaller pot requires much more watering, and if you can't give it then obviously the crop will suffer.
