Need tips on what to buy next

[Hybrid]

I'm finally done with my first project and got 4 autoflowers from a mix from Zenseeds(was 7 seeds but 3 died in the birth)
Have no idea what they are but looks like two are Indica-dominant, one looks like 50/50 and one are Sativa-dominant

Really got surprised how much the Sativa stretched, it doubled in size and got 70cm tall
The Indicas and the 50/50 got 37, 43 and 50cm

They all got pollinated with a Hofman and now I finally have seeds to start my breeding plan with
Ok, I have no illusions I'm able to make something special at first attempt but at least I now have an opportunity to breed some strains suitable for my climate(short, wet and cold summers)
So what I'm gonna do is to buy some nice strains from a known breeder and pollinate them with pollen from my homemade strains

So what I need is tips on which outdoor strains to buy to develop my project
Summers are as said short(June 1st- to end of September, frost come in October), usually wet and cold. The only positive is the daylenght(Scandinavia)
Need an Indica for my sleep and a Sativa for recreational use, only personal use so yield is not as important as health and quality. I also prefer low odor for the stealth growing
