Replacement chain for old Shimano 3x7 STX

I have an old Raleigh MT-200 (which I love as if it were the Old Faithful), with a Shimano STX set.. As per the chain checker tool, I need a replacement chain.
I found mostly that Shimano CN-HG40 may be the right part. In this respect, I have several questions:
  1. Is it the right part? In a Shimano page it is mentioned that it is "for precise index shifting on 6, 7, and 8-speed HYPERDRIVE SIS and DUAL SIS drivetrains." I am not sure it is ok for me.
  2. If not, what is the right part?
  3. Are there many alternative models from Shimano, which may work well. If so, what should I consider to choose?
  4. Are there alternatives from Shimano which already come with a quick link?
  5. What are other good alternatives, from other brands?

I'd suggest you get an 8 speed chain from SRAM or KMC. They both come with quick links. Even the least expensive will be fine.

I'm partial to the SRAM PC-850. It's their least expensive 8-speed chain with chrome-hardened pins for long life.

Any 6/7/8 speed chain will work just fine. KMC, SRAM, Shimano, are the usual suspects

Any 8-speed chain will work. 6/7/8-sp uses the same chain, so no need to hunt down NOS 7-sp.

KMC Z-series or SRAM PC-800 series. You may find different models, like PC-830, PC-850, but that generally refers to the finish (black, silver, nickel, etc) than any real structural or performance difference

Chain checkers can tend to cause one to replace chains before needed.
IF the checker says it's bad, THEN it's time to measure with a ruler to confirm.
I like to measure a 3' section of chain to get a bit better resolution than measuring 12".
1/16" per foot is worn out.

I've used the SRAMS 8XX (830, 850, 870) chains in the past with no problems. Their quicklink can be removed with your fingers, no special pliers needed.

KMC Bicycle Chains | Road MTB Gravel 12spd 11spd 10spd & more (kmcchain.us) Mostly finish (nickel plated, gold, grey finish, etc.) and weight. Very little difference if any in durability or performance between KMC's more expensive chains and their cheaper ones.
