Just get your hands dirty. Researching genetics is going to bottleneck you with a quickness. I'd bet my life on any bean you can get being 100% a modern exotic hybrid. In other words, genetics is a fool's errand until you have a unicorn in hand. Until then, you're talking about lofty theories and ideals without ever going head to head with the incredible amount of variety that each seed, as an individual, will have.
Give me whatever you say is a complete landrace indica. I'll steer it and chop a little early, and it'll hit like an anxiety hammer sativa. Give me your """"""""sativas""""""""" and I'll grow you some couchlock with it. In other words, nearly everything you're gonna come up against researching genetics is garbage in...garbage out, and thats business beratna.
A good starting point for getting a meaningful understanding of the plant (which will immediately put you above at least 99% of budtenders and folks in the industry who aren't cultivator leads) would be things like varietals, cultivars, phenotypes, genotypes, chemotypes, then look at the interplay between microbiome (namely endo-) and chemotype outputs from the same inputs....that is where you'll really go 'wow, nearly nobody knows jack squat about this plant and they're all just parroting anecdotes and bro science'. There are some wild ones out there, with correlations for specific conditions and specific cannabinoids (like that novel one Compound just found where the entire sample group with IBS reported relief like no other)...but there is no X strain for mental illness or condition Y...that entire line of thought is derived from terpene wheel horsecrap. Terpene wheels represent only isoprene based secondaries for the plant, which is not going to link back to medicinal uses.......if it did, we'd all have DoTerra subscriptions instead of health insurance beratna. And EVEN IF it did work like that (which it doesnt) then how do you mesh your condition X with a clinical definition of condition X because your body, as a mathematical boundary value problem extremely vulnerable to perturbations, is quite literally a unique system. If you don't believe this, then you can look into bifurcations and how solution sets to the same problem can display drastically different behavior...aka YOU are an individual, as much as that bean is.
I am sure the plant has much more love for you awaiting on your journey.
