Iirc means "if I remember correctly".
I've checked now and made my (older) Sparrow connect to Bitcoin core, so I can give some more advises.
My blockchain is on g:\Blockchain, please adjust your path accordingly.
My bitcoin.conf looks like this:
txindex=1
server=1
dbcache=8000
rpcbind=127.0.0.1
rpcallow=127.0.0.1
You probably don't need dbcache setting or have to set the correct value for your computer.
I don't know if you need txindex=1 (I think/hope that you don't need it) please set it only if nothing else works (I need it for other things, it needs a full rescan i.e. a lot of time, it takes some extra gigabytes on the HDD)
Something more. You may need to create a new wallet:
bitcoin-cli.exe -datadir=g:\blockchain createwallet sparry
And then in Sparrow it looks like this:
