She has the basics. She used the Psyche-Magnetron on herself and ended up with flight, super strength, super speed, and "enhanced perception" that allows her to track down unique energy signatures like Carol. She's also constantly using Kree weapons for various scenarios, including energy blasting gloves that mimic Carol's energy projection abilities, teleportation tech, cloaking devices, etc.
That might be part of it, but I also feel like Marvel has their go-to players for VFX and post-production and the like, and the A-team was busy with Infinity War, so Black Panther got the B-team, so to speak. That could very well happen with this movie, too, but one aspect this has in its corner is that BP's cinematographer, Rachel Morrison, while great, was also new to the whole VFX game as well. By contrast, Captain Marvel has Ben Davis, the MCU's MVP of cinematography (imo), so he's VERY well-versed with this rodeo. Then there's the nature of the VFX at hand - Captain Marvel will be doing more outlandish things than BP, so that stuff's actually easier to pull off than, say, digital doubles doing martial arts, because we know what the latter should look like. So I think this has at least a couple things going in its favor in terms of the VFX in the final product.
It actually would be amusing to me if she saw Chewy again after 22-25 years and just made some flippant, off-handed quip about it like, "damn, how young were you when I got you?!" And then he's revealed to be an alien in a sequel.
