Lightworks hands down has the absolute best workflow for cutting and assembling video. Nothing else comes close. But like you said, they want you to pay for for anything above 720p. The downside is that it is really slow on my Core i9 Mac with 32 GB memory. The forums lead me to believe this is just an issue with the Mac platform, so Windows and Linux user probably don't experience this. I'm not saying it is slow at playback or seeking—it is really just the UI that's slow like there's a noticeable latency from a click to when a menu appears and don't even try dragging stuff around.
Avid Media Composer is also free but limited to 1080p and has many other limitations that can make it tricky for all but the simplest projects. Again, if you pay up you get what Hollywood editors use, but at $20 to $50 per month subscriptions isn't great for occasional use. It requires some setup and configuration that's not intuitive. I had to google how to have it use only one display and not to just assume I want it to take over all attached displays. It also has a bunch of DRM and copy protection crap that requires a bunch of additional programs and runs permanent Java processes.
Blender has a video editor. That much is true. It just isn't very good. Editing is imprecise and clumsy. You have to manually add frame allotments to the timeline if you go past the runtime. It's only saving grace is the ability to do 4K (probably higher if you want). There's no previewing a clip before you place it on the timeline. All editing is done on the timeline by positioning the playhead. There is an upfront cost for proxy editing, so if your source material is high resolution and long, expect to wait a long time for it to process the clips before you can play or edit them. I've found that when performance starts to suck you'll have to manually rebuild the proxies—maybe go to lunch.
I haven't tried Kdenlive, but its editing ability looks similar to Blender in that you have to put the clip on the timeline before doing anything. Coming from Lightworks or Media Composer this workflow sucks. I'm still going to give it a try, but I'm not sure it is for me.
