In one-year leagues, my personal strategy is this:
In H2H:
Forwards early & often. In several drafts, I took forwards in 5 of the first 6 rounds.
Goalies next, depends on size of league. I don't think you'll need a top tier goalie to win a shortened season. Guys like Niemi, Kipper, Pavelec, Varlamov, Anderson - they can all be had late and all will put up solid numbers, in a weekly H2H, they'll beat the Lundqvists & Rinnes in 40% of match-ups, which ain't too bad.
Defensemen last. In Hits/Blocks leagues, you can wait... wait... wait... and draft some serviceable PIM/Hits/Blocks guys like Mark Stuart and Kyle Quincey very, very late. Drafting defensemen late allows you to concentrate on quality forwards & decent goalies.
In Roto:
Same strategy, but you have to bump up your goalies much higher.
The main difference between H2H & Roto is goalies.
In ROTO, you are working with a full season of goalie standings... so your goalie's SV% and GAA have to be excellent.
In H2H, the week-to-week statistics of a goalie will vary greatly and even Lundqvist can have a bad week that loses an H2H playoff week. SO - stock your skaters to ensure you win almost every skater category. SOG/PIMS/Hits/Blocks are "high quantity" statistics. If you draft those players, you'll win those categories. "Low quantity" statistics like goalie games, +/-, and SHP will vary greatly week-to-week, so don't invest too high in them in H2H.
Good luck.
