I'm not sure what you mean about the view from far? Sims 2 has always only had two views in CAS, looking at the whole body or in close to the face. I guess if you've only played Sims 4 I could see how annoying this would be, but it's not an error in design, it's just 20 years old.
IKEA missing is bad, but I don't think it's their fault. It's safe to assume it's because they couldn't renew the license to include it from IKEA. But, if you have a copy of the IKEA pack, you can install it yourself. I copied it over from Ultimate Collection. If you google GitHub Sims 2 Ikea Legacy, there's a tutorial on how to do it. There's also a couple Reddit threads.
As far as the package installer and bodyshop, I agree with you there. I'm not surprised we don't have them since UC didn't have them either. But they absolutely should have included them with this release.
If you are open to third party programs I've been using Sims2Pack Clean Installer for a decade and it works well. There's also an installer to make Bodyshop work with Legacy on Mod the Sims site. I haven't used that myself, but the feedback appears to be largely positive.
