I find it hard to even start thinking about this scenario, as even some definitions are vague and stand in the way of modelling it. But let me try to disassemble some of it and maybe it will answer your question.
First Venus sized exomoon. It surprised me, but at the moment there is not an universally accepted definition on moon - planet system and binary planet system. In fact by some definitions even Earth-Moon system is in fact binary planet system, but I digress. One that seems to be fairly popular and makes an intuitive sense is the definition by barycenter, I.E. if the barycenter in within the radius of the planet, the other object is a moon, if it is outside, it is a binary planet system. 788
This means that for a Venus like planet you need a fairly big primary planet my napkin math points to some gas giants or similarly massive rock planets.
One thing that will cause most troubles I think, is your 2nd condition. IF we use the Sun for our solar system, AND we need to stay within Goldilocks zone, then for a year log day night cycle, we will need our planet moon combo to be essentially tidally locked with sun. And tidally locked Goldilocks planet is not a great place of life to evolve. Any thriving takes place at the twilight zone which moves around the planet around the year.
Good news is, that you will have plenty of wind, as the air at the sunlit side gets heated up and rises, which pull the cold air from the sunset side giving you ever-present low altitude extreme winds towards the point of the moon that experiences high noon and at the same time high altitude winds towards the cold side of the planet.
In general tidal locking takes place AFTER the molten core of the planet solidifies, so this might be a problem, but it is apparently not a rule, so there can be some plate tectonics.
As with sees, the tidal locking would make the ocean situation very stable, and depending on your crust shape, I don't see why you couldn't have mega lakes. They would however be shifting quite a lot depending on whether they are facing the sun and evaporating rapidly or point away from sun and are frozen solid.
As for blue colored plant live, I honestly don't know hot to even guess. I would assume some fast growing weed/moss just might grow fast enough to stay within the twilight zone and keep shifting around the year, but ... this it too theoretical even for me
TLDR: Venus like exomoon- Plausible, windy- very plausible, year day night cycle - plausible, blue plant life - no idea, tectonic activity - plausible, giant lake-like oceans - no idea. 208
