Should I get the 34mm or 38mm Watch Series 5?

The Watch Series 5 comes in 2 case sizes — 34mm, 38mm. Which one suits you depends on the flat width of your wrist rather than preference: the larger sizes need a wider wrist to sit inside the edge.

TAG Heuer Aquaracer Professional 200 Solargraph 34 Stainless Steel - Rose Gold / Grey - Diamond, Tissot Ballade 34 Stainless Steel - Rose Gold / Silver / Bracelet, Certina DS Action Diamonds 33.8 Stainless Steel - Yellow Gold / Black MOP, Omega De Ville Master Chronometer 34 Stainless Steel - Diamond / Green / Bracelet all sit within half a millimetre of the Apple Watch Series 5 - GPS + Cellular Stainless Steel Case 40mm's 34mm case, so they cover the same amount of wrist.

What is the lug-to-lug of the Apple Watch Series 5 - GPS + Cellular Stainless Steel Case 40mm?

40mm, against a 34mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
