Expanding macro defined by csdef to define a style via tikzset

I need to store tikz option in a csdef:

csdefMy Node Optiondraw=red, thick, fill=yellow

How do I use this definition to define a style via tikzset?
I attempted to use .expand once as per How do I define tikz styles with a xkeyval command?:

tikzsetNode Options/.style/.expand once=csuseMy Node Option

but that leads to a

Package pgfkeys Error: I do not know the key '/tikz/draw=red, thick, fill=yellow' and I am going to ignore it. Perhaps you misspelled it.

The desired result is to modify only the tikzset in the MWE and obtain:

enter image description here

Notes:

As egreg commented, spaces in names of commands should be avoided. However, in my actual use case, the command names defined by the csdef are named after file names with paths which include spaces, slashes, numbers, periods.

Code:

documentclassarticle

usepackagetikz
usepackageetoolbox

begindocument


csdefMy Node Optiondraw=red, thick, fill=yellow

noindent
begintikzpicture
 tikzsetNode Options/.style/.expand once=csuseMy Node Option%% ????

 node [Node Options] at (0,0) Node Text;
endtikzpicture%
enddocument

You'd need /.expand thrice, which doesn't exist. But /.expand twice=csname My Node Optionendcsname works. I know that spaces in names of commands and options is bad. ;-)

You can use expanded instead of expand once in your MWE:

tikzsetNode Options/.style/.expanded=csuseMy Node Option%% ????

+1 It's better to give a complete minimal working example as an answer to show that your solution works, but I agree that this does work and hence that this is probably the preferred tikz solution.

csuse... is not quite the same as csname...endcsname:

% etoolbox.sty, line 883:
newcommand*csuse[1]%
 ifcsname#1endcsname
 csname#1expandafterendcsname
 fi

If you expand once in your context you get

ifcsname My Node Optionendcsnamecsname My Node Optionendcsnamefi

A further expansion step will remove the conditional, leaving

csname My Node Optionendcsnamefi

which requires two expansion steps in order to deliver

draw=red, thick, fill=yellowfi

but then the fi kicks in, because it is shuffled around at the wrong place.

You can do

tikzsetNode Options/.style/.expand twice=csname My Node Optionendcsname

that avoids the problem of the dangling if.

However, the best strategy, in my opinion, is to use styles all around:

documentclassarticle

usepackagetikz

begindocument

tikzsetMy Node Option/.style=draw=red, thick, fill=yellow

begintikzpicture
tikzsetNode Options/.style=My Node Option

node [Node Options] at (0,0) Node Text;
endtikzpicture
