You can't really go wrong with a good 50/50 hybrid. I think it just really depends on what you like. If you have limited experience sometimes it's just hard to know what you like, so you gotta just throw your hook out there and hope.
I would look for something tried and tested. Predictable. As a starting grower, You really don't wanna have to pheno hunt IMO. Getting some clones is a great way to get started since, if you get all the same strain - it's all the same pheno. Someone else hopefully more experienced with a larger operation and more time did the pheno hunting.
Once your able to get through grows successfully, without any issues, and maybe have an extra mom room, then start ordering seeds, and finding your gem.
Until then, I think you should just focus on growing clones, and getting good at growing. Then focus on seeds. It'll be worth your time.
Also, learn to clone. Get good at it. Be able to clone anything. Then start playing with seeds.
