Nope, neither. Both LH FQTV and UA Premier are * Silver which give you no reciprocal lounge access.
With only 35K, your best bet is probably going to be AC. Doesn't look like you will fly enough to get SEN on LH (needs 100K, and even with 200% in C, you still need to fly 50K). Without SEN, no lounge access on other * carriers.
However, 35K gets you AC Élite, which will suffice for * Gold, which gives you lounge access across *.
