To be honest, what seem to be most of your wishes and complaints won't be answered by a new receiver, or at least effectively.
HDMI ports haven't "improved" any in way way that would improve the picture or sound.
To improve the overall sound, you should be looking at new speakers, particularly the front mains and possible center.
For streaming, a Smart TV, most modern Blu-ray players and even inexpensive Roku type boxes afford more streaming options than you can shake a stick at.
