I have the Magic Initiate (Wizard) feat for my character from the Sage background, and whilst the lvl1 spell show up as "use" that can be used once per long rest, they don't show up as "cast" to be castable with my spell slots.

I believe this should be the case, as the part about lvl1 spells of the feat says:

"Level 1 Spell. Choose a level 1 spell from the same list you selected for this feat’s cantrips. You always have that spell prepared. You can cast it once without a spell slot, and you regain the ability to cast it in that way when you finish a Long Rest. You can also cast the spell using any spell slots you have."

So I should always have the spell prepared and be able to cast it with my spell slots, but I can't.

It also sounds very similar to the spells gained from Elven lineage, which do show up as both use and cast:

"When you reach character levels 3 and 5, you learn a higher-level spell, as shown on the table. You always have that spell prepared. You can cast it once without a spell slot, and you regain the ability to cast it in that way when you finish a Long Rest. You can also cast the spell using any spell slots you have of the appropriate level."

So I don't believe I'm misinterpreting any rules here

You're interpreting the rules correctly; it should be available to cast using spell slots. This is a long-standing bug wherein D&D Beyond can't provide that "cast" option for a spell granted by a feat if it's a spell you can choose.

However, all the "cast" button does is check off the spell slot box for you, which you can just do manually.

 Ah, that's annoying, and weird that they can make it work for species but not for feats, but thanks for letting me know

Whilst what you say about manually ticking the spell slots is true, what particularly annoys me about this is that in this case it's a ritual spell, but because it's not listed as a spell that I can cast (only "use"), it doesn't have the ritual symbol next to it either and isn't listed when I filter on prepared ritual spells

That part about the ritual tag may be a holdover from the 2014 rules, where ritual casting was something only enabled by class features and didn't necessarily apply to spells you got from feats or species options. It's definitely something they should fix.

 Ah okay, hopefully they'll fix it soon (and whilst they're at it, they should still look into fixing that it's not listed as a normal casting option)

For now, I've just modified the name of the spell for my character to include "(Ritual)" behind it to remind myself that it's a ritual, not quite a solution (it's less easy to identify and doesn't show up when filtering for rituals), but it's the best I can do for now

It's not an issues of species vs. feats. This scenario occurs when the spell is chosen by the player because there's not yet a good way to have a single choice display in both ways. As such, it's only set up that way when the spell is not a choice (Guiding Bolt from Circle of Stars' Star Map feature, for example).

 Ah okay, messing around a bit in homebrew species creator with elf as template, I think I sort of see the issue, in that for elven lineage spells are listed in there twice, once it's set up for single use not using a spell slot, and once for always prepared and does use a spellslot. When you change them to spell lists to choose from, it becomes to seperate choices and could be one spell you have 1 use of and another that you have always prepared, when they should be the same spell.

That said, the feat creator just doesn't seem to have an option for having a spell you always have prepared
