FD r7000 is a totally different beast, its a toggle mech, they work very well vs conventional 10/11s front mechs with the huge arm that sticks up, but only for R7000/R8000/R9000> 11s groups. I think current gen tiagra 10 shifter (r5000?) will also work, slight difference in cage width of the 10 vs the 11, but nothing a tiny bit of bending can't fix :P
You need a tiagra front mech, the old gen, 4500 or 4600 series should work fine. For rear mechs with that system try to find an old good 9s mtb rear mech (close enough) or again a tiagra 4500 or 4600 works too. 105 5700 and ult 6700 were both kinda bum groupsets, they rely on having extremely good cable routing and quality of cables, perfect chain (and orientation!), perfect mech hanger alignment and the shifter to have not disingegrated internally*
*Saw loads of Ult 6700 left hand shifters fall apart inside due to a bolt or a nut that the assembly rotates on coming loose. If you catch it in time you can do a DIY fix and it'll be fine, but if you leave it the whole lot grenades itself. RH STI's would just get heavier and heavier, or break due to bad cables/high friction.

Trying to get a Shimano FD7000 to work with 5700 10 speed shifters, I can’t get it shift anywhere close to well, but then again I am also absolutely terrible with front derailleur setup. Are they compatible? I’ve read that the cable pull ratio is slightly different?
