Welcome back to the hobby.
I'd say the simplest advice for kits to stay away from is this, the more it costs the harder it is to build.
Some of the more exotic manufacturers like Zoukei Mura make great kits but they are so complex most people buy them and then get scared of them so don't build many. Also stay away from the bigger scales like 1/32 and 1/24 as these are much more detailed due to the size.
If your looking to get confidence and technique go for Tamiya, newer Revell kits, Hasegawa as you've listed as they have generaly good kits with simple instructions. Instructions can be as important to helping you build as anything else, I'm sure all of us on here have looked at some instructions from Dragon and have had no idea where a part is supposed to go!
Good luck and keep asking questions we all do and we are all learning
