Anyway, if you maintain the tire diameter, there should be no drop to speak of.

Given the measurements that you gave, the upgrade closely approximates the original tire diameter. As such, there will be no significant change in ride height. However, these larger rims will adversely affect ride quality.

but what if the overall weight of the rim/tire is the same as the stock?

for example: larger tires which is heavier but newer rims that maybe wider but lighter so much so that overall weight of the new rim/tire is the same with the stock

will FC still suffer?

In my case i changed from stock 16s with 205 55 R16 tires to 17s with 205 50 R17. Wider & lower tire profile and larger rim with overall height taller than by about .19 inches. Pero yung pinili ko na mags ay mas lighter sa stock. Bago ko ipinakabit yung wheels na-compare ko muna yung weight ng dalawa mas lighter talaga yung 17s. The end result is good response from a complete stop, better acceleration and nag-improve yung FC ko.

May nabasa ako sa ibang forum, to keep within +/- 3% of the overall height pag magpapalit ng rims.

FC due to the weight of the tire/rim combo will be the same. But taller and/or wider tires will also increase drag, also contributing to increased FC. I'd also be looking at the tread pattern. This also affects FC. You'll notice this more if you do a lot of highway driving. The bigger the spacing and less vertical the blocks are arranged, the more drag. If your tires are noisy on the highway malakas sa FC yun. Although if the bigger tires allow you to float over bumps instead of braking for them, FC might improve.

from oem 18's, i already shifted to lightweight 20's. so far no significant difference in FC.

No. Same spec pa rin with the OEM set-up eh. Basta if more on city driving, the smaller lighter wheel/rim combo would be better. For those that do more hway rides, bigger wheels not tires itself would be more beneficial.
