I found these links when I was doing research about creating spending transaction of a multisig address
Maybe it helps
Yes! The trick is to count each input with its effective value rather than its nominal value.
Transactions are composed of three parts: the overhead, the inputs and the outputs.
The size of the output scripts is determined by the recipient addresses, so their size is given by the transaction instructions. We do not know whether we will need a ...
Kind of, but coin selection is hard in general. The idea is that inputs pay for themselves. It is easy to compute how much in fees you will need to pay for an input at a given fee rate. So when you do coin selection, instead of selecting on the actual value of the input, you use the value of the input minus the fees it will pay. This is known as the ...
Check confirmations on blockstream.info
If unconfirmed, open the wallet where you had sent, spend those BTC by sending to another address in same wallet with a fee rate more than what others are paying. Check mempool here: https://mempool.observer

On an uncongested network with an average tx fee of ~20 cents. Which transaction would most likely go through?
The transaction which confirms is the one chosen by the miner which finds the next block. There is no way to know which one they may choose. It may be the first one they saw, or it may be the one with the highest fees, or it may depend on some ...
I personally use https://changehero.io/ exchange platform to buy BTC and other cryptos. I've never tried another exchange platform so I have no idea how to transfer your crypto between two different platforms without fees.
Transactions fees goes to miner along with the mining rewards. Fee is a function of how much transactions are in mempool and several other things.
Using cli of bitcoin node, you can get an estimate fee as per number of blocks time you want for confirmation.
Ex - Let's say I am ok with my transaction getting confirmed after approx n blocks are formed
Transaction fees are paid to the miner that includes that transaction in their block. Nodes do not earn transaction fees (or any other fees) for validating transactions.
You can reduce fees by using segwit inputs, and by waiting for periods when the mempool is relatively empty.
