I'm not sure what type of hardware you're looking to use (i.e. a computer or a smartphone), but the only wallet that will provide you with the ability to do what you're requesting is Bitcoin Core.  I know, I know, 550GB to download the blockchain, but that's the point.  It's not only providing you with the privacy you want, but it's also supporting the blockchain and keeping bitcoin decentralized.  Obviously it's not going to work on a mobile device, but with your own full node running there are ways to connect your mobile wallets to it as well.

You can actually do this for far less than 550GB (and without a node) if someone scrapes all the gz.blockchair.com dumps for the Bitcoin chain and distributes it in a usable form, because it contains all the inputs/outputs, transactions, blocks, etc. and even address data for each individual day. Of course, you still have to rely on this dataset to be correct, but the worst that can happen if someone screws up is simply that broadcasted transactions get rejected.
