Importing 16 bit file into 24 bit project

Question

Whats up guy's
When importing a 16 bit file into a 24 bit project
should I convert the file to 24 bits or keep the
original 16 bit depth?
I'm aware that the sample rate is converted to the
projects sample rate when importing files as long as
the corresponding checkbox is enabled in the project
settings - assets pane.
I'm also aware that conversion can be done at a later
state after importing, but I'm curious about the best
or proper approach. Should this be done prior to importing
or should the file be kept in it's original state (16 bits)?
PS - If you could provide the chapter or page of the manual
this information is on that would be extremely helpful.
Thnx in advance

When you say "alter the file's sample data" are you referring to
edits done in the sample editor or sample rate conversion?
both would qualify. there are some corner cases where bit depth does not matter when destructively editing sample data (as I outlined in my initial post).
If you're talking about the sample editor do you mean converting by
saving a copy as 24 bits and making edits to the copy might show tiny
improvements?
yes.
At this moment I don't intend on destructively editing the file but
you never know how processing and mixing might go until your done.
ok. if your file is read and processed in realtime (or via a frozen track) then there's no loss - logic will convert audio samples during playback to a 32 floating point representation as it is read from disk, before it enters the mixer, or is processed by your plugins.
i'm not sure if source bit depth determines bounce in place format- if so, and if you use this feature, then you should convert the source to 24 bit.
the end point is: unless you are desperate for disk space, just convert it to 24 bits. 16 bits is very 'last millennium' in modern production stages - there are a few exceptions to that (e.g., if the files are used by a software sampler, or if the format is required for compatibility with other hardware or software) but... most of the strong arguments for 16 bit died years ago. so, i'd say it's best to consider 24 bits as the minimum during production unless you have very specific reasons to go below that (and you fully understand the tradeoffs). if you want to know the 'whys', that's fine, of course. curiosity and knowledge don't hurt. if you're only looking for a recommendation, that's my recommendation.
