For tripod, there are a number of factors to consider:
1) Load capacity
2) Max height (fully deployed)
3) Min height (folded)
4) Number of sections
5) Weight
6) Price
is a gd guide for me. thank you.
1) support til 3kg
2) 1.8m
3) No idea. ( will find out more)
4) 3-4 sections
5) 1-2kg
6) $300
Some reality checks ...
A tripod, when fully extended, will NOT be very stable.
A 3 or 4 section tripod, weighing only 1-2kgs, reaching up to 1.8meters, could be very flimsy, because the legs' OD has to be thin, and those have to be thin-walled. Locking mechanisms might be compromised, especially at the lower price-points.
Don't think any reputable manufacturer would offer something they know will be shaky because their reputation is at stake. Also, the more sections a tripod has, the less structurally stable it becomes, especially when fully deployed/extended.
Ideally, you want a support system (including the head) to be capable of taking at least 2 - 3 times the manufacturer stated max loads, and also be able to reach a desired working height WITHOUT being fully extended. Margins of what is ideal would vary greatly with individual tripod design and actual construction, but my guess is (with good designs and stable engineering) I would max a tripod to between 50% and 75% of its extension capabilities
without raising the center column.
In your case, that would mean a system with a max load of 6 - 9kg, and a max height of more than 2meters.
Also bear in mind, especially if you shoot in windy conditions like atop the Pinnacle or the new MBS skybridge, the higher any tripod is, it's far more susceptible to a multitude of movement and vibrations.
Might have to re-evaluate your requirements. I may be wrong, but I don't think you will find a 1-2kg tripod with head fully extended that meets those requirements even if you were willing to pay $3000 instead of $300.
This assumes a premise that you want a stable tripod support system, and not just something to plonk your camera on.
