LuaTeX and XeTeX use harfbuzz as OpenType rendering engine. On
LuaLaTeX and XeLaTeX you must use the fontspec package
(https://www.ctan.org/pkg/fontspec) to load otf or ttf fonts and add
opentype features. It is very powerful and its interface is very simple
to use. XeTeX has access to system fonts. LuaTeX has access to both
system fonts and any font you want to declare, simply by adding the
path.

For example:

\setmainfont{Palatino Linotype}[Ligatures=NoCommon,Numbers=Lowercase]

With LuaTeX you can also define new opentype features on the fly using
scripts in Lua, via the function fonts.handlers.otf.addfeature

For example, here I define a character substitution:

\directlua{
fonts.handlers.otf.addfeature{
name = "mysub",
type = "substitution",
data = {
periodcentered = "anoteleia",
},
}
}

And here I add that feature to Linux Libertine font:

\setmainfont{Linux Libertine O}[RawFeature=+mysub]

For multilingual management I recommend using Babel instead of
Polyglossia. You can, for example, assign with Babel families from fonts
and language definitions to non-Latin scripts (Cyrillic, Greek,
Devanagari, Arabic, etc.). For example

\babelprovide[onchar=ids fonts,hyphenrules=russian]{russian}
  \babelprovide[onchar=ids fonts,hyphenrules=ancientgreek]{greek}

\babelfont[russian]{rm}[%
  Numbers=Lowercase]{Linux Libertine O}
  \babelfont[greek]{rm}[%
  Numbers=Lowercase]{Old Standard}

Best regards,

Juan Manuel
