Central Europe - outdoor strain growing

Hey guys, im a complete beginner in growing cann so all my info comes from websites and YT. I would love to try to grow some strain outdoor (mild climate of central Europe, 50l pot or free ground). What do you think is for me the easiest high-yielding plant to grow next year? I dont want autoflowers, prefer resistant types. Thank you for your advice

P. S. Though of the Hollands hope. Good idea?

There are many reports that hollands hope has gone to shit over the last few years. I can recommend the sweet seeds fast versions, hybrids from hell, female seeds (easy sativa, grapefruit, c99), real gorilla seeds, kalashnikov seeds fast versions or la buena hierba. If you want to stick with dutch passion I would recommend frisian dew, durban poison, passion number one.
