If no one has suggested this so far... ensure your house is clean, tidy, no marks etc. Clean towels, toilet etc. if you have pets ensure they're either out of the way or hair hoovered up.
No need for anything like a wine decanter at all.
Things like hand soap and hand lotion impress me as a guest. Lotion not necessary.
Nice candle lit - preferably relaxing or 'fresh/zesty' one.
Maybe an ornament that's a talking point. or even a funny inspirational quotes etc print if you see a nice framed one that's within your budget and you'd buy it anyway.
One thing I would change if your cushions are old/tatty etc - and I have been known to change them - you could change those - otherwise if pets go on them, hoover free of hairs and/or wash.
Nice glasses always good - preferably matching but doesn't have to be that way.
Napkins/serviettes - paper or material ones - if material ensure they're clean and if possible ironed/pressed but not essential. Also tablecloth or runner if you're using tablecloth.
nice charcuterie/potato salad/crackers/bread/pate etc - whatever you feel is nice and will go down well, if you're looking to impress then quality over cheaper items.
also for after drinks - some sort of mini dessert/cake or chocolates - mini florentines maybe.
Dinks - as blitzen says - a gin based cocktail is a nice starter but this is if your friends like gin! I'd go for a nice cava/prosecco.
