Diez Vistas. (One of the easier ones, transit accessible.) More hiking in the area, Dilly Dally may be beyond your desired difficulty (more from length and trail-finding, not technical scrambling) but up Polytrichum and the loop clockwise around the Lake District fits the bill.
Consider Hanes Valley. Also transit friendly, stats may sound mild but it's plenty tough.
If a long day with much varied activity, not just hiking sounds good perhaps a day-trip to Bowen Island would work. Don't bring a car!
Not transit accessible, but both Seymour and Cypress have extensive trails covering all lengths and difficulties.
