Back in 2019 some releases installed directly from IGG-GAMES contained crypto miners. They also added their own DRM to releases. Since then I have stayed away and never looked back.
hallowed is the internal release group at MTV. Their aim is to produce highly streamable (think Plex/Jellyfin) but still high quality encodes. They also always include English subs and dual audio for foreign films. The quality of their releases are good but very few as they only started releasing under that name about 5 months ago.
However, if you are gunning for highest possible quality/bitrate (and file size) you can get, go with releases by CtrlHD, MainFrame or W4NK3R.
FraMeSTor is the internal group at BHD. EPSiLON was previously releasing on PHD but left a couple years ago. They release to TL but are not nearly as active as they once were.
I prioritize FraMeSTor, and they have more releases post-2020.
Cloudflare’s CAPTCHA is Turnstile. I’ve found it very useful. It doesn’t use pick the image or type the text, it’s just tick the box. You can even set it to invisible, then the user doesn’t need to even do that, the challenge is sent to the browser and is completed automatically.

In terms of privacy, it’s is still Cloudflare, but at least it’s not intrusive to the user experience.
You can but you don’t need to. All they really do is organise everything. Any requests go through Prowlarr/Jackett which do the API calls then push that to qBit. One could argue you should put Prowlarr behind a VPN as well but it depends on the trackers you have in there.
