I think what I'll miss is having 20-year-later eyesight, so working on intricate details with artificial light will be less appealing. (By now I know what my dad would mean when he'd say things like "how can you see that in this light?") Once I've finished a more important assignment, I'll push my work-from-home hours to the mornings and evenings, leaving the afternoon free.
If the isolation should somehow continue to the winter, I'll also miss out on evening daylight, since I live 4° further north.
