My first stringed instrument was a uke, bought in 1968 in Matchetts, Belfast, for the princely sum of 1 UK pound.
I currently tutor a small group in U3A at Gransha, 11.30 a.m. Mondays.
A couple of weeks ago we entertained about 50 OAPs on a train trip to Coleraine as part of Positive Ageing Month promoted by local GPs.
We also have an upcoming gig as part of the Guildhall Christmas Craft Fair.

The naming is determined by scale length (distance from nut to bridge saddle) Soprano-14", Concert-15", Tenor-17", Baritone-19".
These measurements can vary but are a reasonable guide.
The original instrument was Soprano sized and was a Hawaiian version of a small instrument brought over by Portuguese migrants ( Machete )
You are correct about the tuning intervals though in the early 1900s, a D F# B was considered standard. With g C E A tuning your guitar D chord becomes G,
F becomes Bb, etc. As Mario said everything is a fourth up.
The octave higher 4th string is called re-entrant tuning and is what gives ukes their distinctive sound.
For melody linear tuning would give you greater range than re-entrant, but you lose the distinct sound.
In my opinion Baritones can sound like a typical small guitar marketed for children, they're neither one thing nor the other.
I would recommend nothing bigger than a Tenor, but bear in mind that the only scale for gentlemen is Soprano wink

Since we are in the same neck of the woods, why not drop in and see us on a Monday session.

Good Luck

re the Song book you mentioned, I've seen that and several others, all of varying accuracy.
These seem to be put together by people "copy and pasting" from various sites without any checking or editing.
I would recommend Jim's Ukulele and Guitar Songs, https://ozbcoz.com/Songs/index.php# as a good source to compile your own song book from.
