My favorite strains to grow outside are all Indica leaning. I do this because Sativa always take the longest to flower and sometimes they are not even ready by the time frost is hitting. You are talking about a few weeks of time outside with an Indica vs Sativa.
So my recommendation is whatever strain you have going now, to choose whatever one is more Indica leaning.
Also, I would like to note that Sativa plants are usually the 10-12 foot monster plants you see on the internet. Whereas Indica will get around 6-7 feet tall in a season.
I hope this helps and I really want to see this journey so hope you keep us posted.
