There are some aspects of the question that can be answered. If possible, I would recommend stepping up to a direct drive trainer if you can. With this type of trainer, you remove the rear wheel, and you put your chain on the trainer's cassette (you will almost certainly want to get a dedicated cassette for the trainer). You may or may not need to adjust the derailleur cable tension and limit screws when you put your bike on the trainer. My bike doesn't need adjustment.
With a wheel-on trainer, you clamp the rear end of the bike in the trainer, and you put the trainer's roller in contact with the tire. These trainers are less accurate, and in particular they're more sensitive to how much pressure you put on the rear tire. In the Zwift racing community, there is a lot of dissatisfaction at people using wheel-on trainers who appear to generate implausibly high power numbers for their racing category (mostly a problem with new Zwifters in cats C or D, which are beginner categories). However, not everyone races, so this may not matter as much to you. Wheel-on trainers do generally offer a less realistic ride experience, i.e. it feels a bit different pedaling on the trainer than on the road, and they do wear your rear tire out (so many people use an old tire or a trainer-specific tire).
Direct drive trainers used to be a significant step up in price. The Zwift trainer you mentioned is a significant development, because it's from a major company at a very aggressive price point - although, as noted in comments, it is actually a rebrand of a trainer by a less-known company. Two well-known reviewers are DC Rainmaker and GP Lama (the latter hasn't reviewed it fully yet). You can generally rely on them for comparative product reviews. The Zwift trainer may cause other companies to discount competing trainers (e.g. Wahoo's Kickr Core). DC Rainmaker seems to strongly recommend the Zwift trainer if the company can sort out some accuracy issues with a firmware update. He seemed to think that they should be able to do this. GP Lama was much more cautious on this issue, and he had reviewed the Jet Black Volt (which the Zwift trainer is a rebranded version of). So, those are the issues to consider with lower-cost entry level direct drive trainers, whereas I think the Kickr Core and equivalent trainers were mostly OK from launch.
