Is the PX700HDH good for a first home theater?

Yes, if you want a simple 1080p picture. It has no smart apps or HDR, so you add a streaming stick through HDMI.

Does it support 4K or HDR?

No. It is native 1080p and does not accept or display HDR content.

Only vertically. There is vertical keystone and zoom, but no horizontal keystone, so keep the projector roughly centered on the screen.

No. There is no app control or smart platform; plug a streaming device into the HDMI input.

The projector and a remote control. Check the listing for the power cable and any documentation.

Yes. There is a 3.5mm audio output, and the built-in speaker works for basic use.
