I have no experience with the FT-1000, but I do have a fondness for classic rigs. They're fun to operate for a while, but can get tiresome after a bit. I prefer a more modern rig for my "daily driver".
That having been said, I recently upgraded from an IC-7300 to an FTDX10. The difference is night and day. The FT-710 layout and specs are very similar to the FTDX10. The main difference is that the 710 is a direct sampling SDR, just like the 7300.
In my opinion, the 7300 is perfectly adequate for SSB and casual CW operation. For more serious CW ops, it would not be my first choice. The filtering and audio peak filter in the Yaesu rigs make a huge difference in the CW performance. I also think the Yaesu DNR is superior to the Icom.
The stock mic on the 7300 is awesome. The Yaesu stock mic is just okay.
On the 7300, you don't need any of the options you listed.
Regarding the user interface, don't be put off by the Yaesu system. It's easy enough to learn after reviewing the manual. The 7300's interface is initially easier, but some functions, like switching from paddles to a straight key, are actually easier to execute on the Yaesu. Two key strokes on the Yaesu; four keystrokes on the Icom.
The antenna tuner in the Yaesu is more forgiving than the Icom. It's rated at 3:1, but in reality it's closer to 5:1. The Icom is barely 3:1, unless you switch into emergency mode, which limits your output power to 50 watts.
As always, YMMV. For someone just returning to the air, either the 7300 or 710 should make you happy. Pick the one that best fits your interests.
