I'd like a philosophical one; where would I look?
The irregular rites worked by people who are really on it.
Depends what you are looking for.
The Grand Orient (mainly France duristictions these days) is secular masonary.
Under the grand Orient you have Co-masonary which teachs Theosophy - this might operate in US, don't know. its in UK but small and a bit

Fascinatingly, The Eastern "Freemasons" the Al Bana, "The builders" worked an identical system to masonary which predates ours. Exactly the same 3 degree system. No Solomon of course
The Egyptian Rites of Memphis and Mizrain are not performed in ritual form these days, but the rites and charters are still worked internationally by a number bodies.
The most philosophical masonic order in existance imo today is the OTO. The Co-masons are cool, but Theosophy is to simplisitc for me. The OTO started off as the Mysteria Maxima Masonic (M.'.M.'.M.'.). It was a masonic academy formed in 1912 as a commendium and contains all the teachings and secrets of all the masonic rites in existance at that time.
They took all the confusion, 33 degrees here, 97 there and turned into 10.
The first 4 of which are equivalent with those the Blue Lodge Craft (Birth I, Life II and Death III ), with the addition of a precedant degree Minveral (Conception 0 ).
The forth degree (IVth and P.'.I.'.) is equivalent to the Royal Arch and Prince of Jerusalem.
After these degree from 0-IV and PI, the system can be equated with the degrees of the Scottish Rite and the Egypation Rits. for Eg the 33rd degree in Scottish rite is equivalent to the VIIth degree OTO.. ad infintum.
The philosophy of freemasonary is simple.
Its the story of Birth, the teaching of Life and the secrets of Death, taught through the medium of initiation. The conttext is irrelevant. The secrets are incommunicable. IThe ultimate secret of freemasonary is doing it. Thats why you can read it all in a book. doesn't mean anything.
The Secret is was happens to your subconscious when you put yourself there and experience it.
I love freemasonary - its awesome. The simple idea we are all rough stones that need to be squared and polished is just lovely. Becoming a freemason is a bit like kicking yourself up the backside :
shut up and get on with it. spit spot!
