[MENTION=12731]CapnZapp[/MENTION] #15 and #18 with 3.5 wealth per Level had a totally different meaning than with 5e. But why did i t have that? Because you were suposed to be able to buy a +3 sword or a wand of cure light wounds with 50 charges.
If you want wealth per Level you Need to introduce some Kind of economy which goes beyond the equipment list or at least adjusts the Prices on the Equipment list. I heavily recommend (also for a greater challenge) to Hand out starting Money instead of the starting Equipment in the phb
Also i recommend to introduce a cost System for those classes who do not have to invest in the most expensive items (heavy armor) on the phb in a meaningful way. (E.g. generic spell component costs, paying for learning a spell, having to Support the church of your faith etc.) and /or do adjust by different starting Money for the classes depending on their Initial Needs like former Editions did.
Since 5E has no such rules at all, and the given things in the PHB are Close to useless (i mean they could have also left out the Prices for items, since they are unrealistic without end), you either can houserule /homebrew things or if you insist on using the RAW only then just Forget about any wealth per Level (like you suggested) because it is not worth it, it does not even give flavor to the campaign or any challenge or micromanagement skills.
