Here is a complete set of province templates for the WRE starting provinces. Remember that these templates are based on Legendary difficulty, and assumes 0 fertility. For details on how I have formulated these tables please refer to Part 1 of this guide.

I will skip Raetia et Noricum, Pannonia and Dalmatia because, well, most of the time they are abandoned anyway and are not reclaimed until much later in the game. Maxima Sequanorum is also skipped here, as it will be discussed separately in Part 6: Specialised Military Provinces.

Ok here we go:

Italia

This is the province template for Italia. There is 10% cultural wealth bonus due to the presence of Rome (a Wonder). I don't really like building Garrison Quarters since they don't provide any income, but I couldn't come up with a better template without it. The limiting factor when doing the mix & match for Italia is the fact that Salt and Port are located in the same settlement, Neapolis, which makes sanitation management tricky.

Venetia

This is the richest province in the WRE, being the only province to break the 16k mark. This is possible due to factors such as: presence of olive (along with wine, olive is the most profitable resource in the game), presence of 2 ports, the fact that the ports and olive are located in three separate settlements, and lastly 10% wealth bonus due to a Wonder (Ravenna).

In the actual WRE game though, Venetia is a border province, so you will probably be busy spamming it with garrison buildings in the early-mid game, especially at Aquileia which is a chokepoint for defending against the Huns. Once the Huns are gone you can start the redevelopment of Venetia to focus more on income.

Magna Graecia

Also a very rich province, due to the presence of 3 ports and wine. Unlike Venetia, Magna Graecia is not a border province, which allows you to develop the area relatively free from external threats. Be careful though of occasional seaborn invasions from your eastern enemies.

Liguria

So-so in terms of income. Do not develop Liguria too early in the game, since it is the no.1 tourist destination for your best friend Attila the Hun. Once he is gone you can start redeveloping Liguria.

Insulae Occidentalis

A 3 port province like Magna Graecia, which means $$$. In Caralis I gave up Tier 4 Fishing Port due to sanitation issues. Having Tier 4 Fishing Port + Aqueduct Network in Caralis will disrupt the entire mix & match, resulting in less income. Insulae Occidentalis is arguably the safest out of all the WRE starting provinces, so develop them from the start.

Baetica

The presence of wine is the source of Baetica's high income potential.

Lusitania

There is no need to develop iron in Pax Augusta. When iron is ignored, Lusitania becomes a typical 1 port province with an average income potential.

Gallaecia

Income potential is higher if you ditch gold altogether (see Part 5 for details). Another typical 1 port province like Lusitania.

Tarraconensis

Regarding marble, it is more profitable to go up the Quarry pathway rather than the Carver pathway. See Part 5 for details.

Carthaginensis

Richest province in Iberia, thanks to the presence of olive.

Africa

Income potential is above average, thanks to 2 ports.

Tripolitania

The dye building is useless by itself, but you need the resource for the construction of some high-tier buildings in the Empire, so no choice but to build it.

Mauretania

Just like dye, timber does not contribute to province wealth, but nevertheless needs to be developed to satisfy building requirements. Mauretania and Tripolitania are 3 port provinces which means they have potentials to become great cash generators for your empire, but because of silly resources (dye and timber) that take up space, the income potentials of these provinces are diminished.

Narbonensis

The presence of wine always boosts province wealth.

Lugdunensis

Exactly the same province layout as Italia.

Belgica

Belgica is the northern seashore of Gaul yet it does not have any ports. Because of this, Belgica is one of the poorest provinces of the WRE, second only to Britannia Inferior.

Aquitania

Using Tier 3 gold building yields the best result in terms of income - see Part 5 for details.

Britannia Superior

Iron can be ignored. Britannia Superior is a typical one-port province, just like Lusitania / Gallaecia.

Britannia Inferior

This is the poorest province of the WRE. Factors contributing to this:
-Presence of only one port
-Lead which doesn't provide any wealth bonus but nonetheless must be developed in order to satisfy building requirements
-The one port and lead are located at a single settlement (Segontium) rather than being spread out, which makes sanitation management difficult
Maximum income potential just breaks the 10k mark.
