Explaining the bug
The bartering with piglings is not working well, it depend on how the player interacts with the mob so now I will explain what happens in different cases.
When right-clicking with a gold ingot, piglins will only give the player flint and steel and obsidian. When throwing gold ingots, piglins only give nether wart blocks.
Piglins should give the following items:
Netherite hoe
Iron nugget
Potion and splash potion of fire resistance
Nether quartz
Glowstone dust
Magma cream
Ender pearl
String
Fire charge
Gravel
Leather
Nether brick (item)
Obsidian
Soul sand
How to reproduce
Look for a piglin or spawn it.
Right-click or throw gold ingot.

Also they drop Crying Obsidian, but need to wait until they add it in the next beta.

if you throw you get nether wart blocks; but if you click you get obsidian and flint and steals

Items that piglins should give but is currently not added:
Crying Obsidian
Iron boots with soul speed
Enchanted book with soul speed
Here are the list of features that piglins barter currently in the Java Edition.

I've read on https://minecraft.gamepedia.com/Bartering that the list of barters you have given above currently only applies as upcoming Java Edition features. What I would like to know is whether they would add the same list of barters to Bedrock Edition later or not.

I suggest they are still developing the complete loot table in Bedrock Edition. The full update is not yet released; this might be just an introduction to the concept of bartering with piglins until they develop all the other barters on Bedrock Edition.

Besides that features are always developed on Java Edition first before importing to Bedrock and developing there later, which is why full updates are released later on Bedrock Edition. I don't believe the features now developing on Java will be denied from Bedrock, since parity was a main goal in this upcoming update.

Fixed in Beta 1.16.0.57
i've only ever been given nether wart blocks. i've flown around in creative throwing gold at everything, and i've never had anything else
