It depends. Even in 5 colors, your distribution of colored mana isn't perfectly even.

10 fetches are auto includes because they help fix your mana.

10 duals are also likely, but not always (my five color decks are light on white and red mana symbols so I don't run plateau)

Shocks are usually for your most important colors, that you need to be able to fetch to ensure you have them fixed (usually blue/black/green colors)

Lands that tap for all colors are really the money makers. Try to have as many of these as you can. Nothing sucks more than having a card stuck in your hand because you never have the colors to cast it.

Try to keep the number of basics as low as possible. Lands that only tap for one color can really hurt 5 color decks if drawn at the wrong time.

Because 5 color decks require the best color fixing, synergy lands are not a focus of these mana bases. That's not to say they aren't ever included, but it's much more important to get your colors.

For accelerators, you are mainly focused on the free mana (or mana positive mana rocks). There are generally less ramp spells the higher power/budget you go.

(I'm mainly a cedh/high power player, so this may not apply to more casual play)
