I also find it difficult to get started with bitcoin wallets because it's hard to find out how much money I have in them.
Well always hold your bitcoins in a secure wallet (e.g. electrum) and for price tracking you can use any other portfolio management app ( it will show you your profit and loss)
These are apps I have been using for managing portfolio
Coin Stats
Coinmarketcap
Blockfolio (Now FTX)
Plus, it's impossible to use them for transactions when traveling abroad because there are so many different types of exchanges.
