I don't have as many hours in LS3s as Papa3, but owned an LS4 for 7 years after flying a 4 owned by P3's friend "The Scoundrel".
The DG300 was my other candidate before that. Flown a couple of those... They don't have the feel the LS has.
The LS4 is one of the nicest gliders to fly, would highly recommend it as a first glider. It more or less does what you think.
Not automatic hookups, but the 4 you need to hook up are easy and have LS-Sleeves for security.
The ****ty Tost drum wheel brakes (many gliders have them) can be relined and arc'd by a motorcycle brake specialist.
The heel brake control is actually a good thing.
The landing gear handle gets in the way if you grab the air brakes with the gear up. Pretty cool.
And it's a very good choice in Club Class.
As others have said, a good trailer is important.
