I know the
tippet/leader/line/rod needs to be sized appropriately to fly size but

No, things are simpler than that.

Light rods (e.g. line weights 6 and smaller can easily cast
fly sizes between # 4 or 6 (e.g. Muddler Minnow about an inch
long) and #18 (smallest size with which you can effectively
"match the hatch" in your first season of fishing.) Lighter rods
can fish effectively even smaller fllies, and heavier ones (e.g.
line weight 7 to 12) are designed for bigger flies, say #14 smallest up
to several inches long. Each has its own range for practical fishing.

Leaders simply taper from (70 per cent of) line tip diameter
down to the tippet, determined by hook size, e.g.
diam. 0.006 inch is best for fly size #16 and possible for #14 and #18
thus diam. 0.007" for size #14
0.008" for #12
0.009" for #10
and use 0.011" for larger flies,
leader length being fixed by function, e.g. only 2 to 4 feet for flies
fished deep on a sinking line, 9 feet or longer for dry flies on smooth
water.

I can't tell what size flies are in my box. Can't find anything on the
internet like a hook size chart.

Try the library. Most book-length guides have a hook size chart,
as do some fishing tackle catalogues, free or on-line.
