I'd go with 5/8 octoplait/brait and 5/16" G43 high-test chain. If you're not getting a windlass, get a good chain pawl for the foredeck, since it will make hauling up the 35' of chain, 33 lbs. of anchor and 30 lbs. of mud that the Rocna will pick up, much more manageable.
I'm speaking from experience, since I have a Rocna 15 on my boat.
Less chain on the Fortress is probably a very good idea, as they don't recommend much more than 12-16' of chain to begin with, and more makes the anchor more difficult to set properly.
Be aware that for 5/8" line, you'll want at least 10" cleats.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
