Is a HDEO required because of the turbo, or can you simply run a conventional 5W30 or similar?
No, an HDEO is not required. I don't even think it's a good idea. Which engine do you have in this thing? If it' the low-boost 2.4, I'd go with an oil that meets Honda's HTO-06 spec, so either Pennzoil Platinum or Mobil1 5W30, EP or regular, 5W30. Since you're doing mostly short trips, there's absolutely no benefit or need to use a thicker oil in this engine. The oil temps just don't get that hot in that engine, and viscosity is directly related to oil temps. Pennzoil Platinum 5W30 would probably be my first choice, but any of those would work well.
If you have the high-boost 2.3L, I'd go with an ACEA A3-rated oil, M1 0W40 would be my first choice based on availability and performance.
You do not need a 10W40 oil in this engine for your driving conditions, and you certainly don't need a high-mileage oil at that point. 200KM is just breaking in for that motor.
