Terran Republic series is about Earth fianlly meeting some alien races after it had expanded to a handful of planets.

Old Mans War by John Scalzi.

Expedtionay force series by Craig Alanson is fun romp around the galaxy. The start in first book is a bit slow and the tone of rest of series is very different.

Lost fleet by Jack Campbell is nice as well. Its more about fleet action and battles.

Terran Republic series by Charles Gannon is also quite good.

Icarus Hunt series by Timothy Zahn was very interesting.

Fuzzy Nation by John Scalzi.

Terran Republic series by Charles Gannon has humans more advanced than one or two, but definitely not at the top of the pack.

Sector General by James White has humans as part of the large alliance of races. The alliance is more advanced than some of the races they encounter.

Foreigner series by C J Cherryh has humans far more technologically advanced, however the small number that reach the alien world have to learn to live peacefully with the aliens.

Most of the Stars wars books have humans as very advanced.
