A soldering iron that goes directly into a wall, with no temperature control, is certainly something to stay away from. I'm not sure what is meant by wattage controlled, but if it's just dimming the power to the iron, without a temperature feedback and control, then that would also be no good.
If you say you'll want to get more serious with electronics and it's not just a thing you want to try out, then a quality Hakko or Weller will be a reliable companion for maybe the rest of your life. So a one time investment in a quality tool can save you money in the long run, also the day to day experience of a quality iron compared to eventual poor performance of a cheapo could also be considered.
But that's not to say there aren’t good cheap stations out there that are well worth the money. And it can also be argued that if you wanna get really serious with electronics then some time in the future you might need a second iron as well, so starting out with a cheap one and getting a good one later on is certainly not a bad plan either. And if in the future it turns out you don't stick with electronics then the cheap station might did just good enough in the meantime.
So sorry, no specific recommendation from me, but if you don’t have the money, buy a cheap one, if money isn’t that important, then it’s still a decision you have to make for your own if you go for cheap or more expensive.
