TikZ node shape depends on inside text

In one of my previous answers, my first proposal



documentclass[tikz]{standalone}
usetikzlibrary{quotes,angles}
begin{document}
begin{tikzpicture}
draw (0,-4)--(0,4) node[above] {$Im$} (-4,0)--(4,0) node[right] {$Re$};
draw[dashed] (0,0) circle (3) circle (2);
coordinate (a) at (80:3);
coordinate (b) at (3,0);
coordinate (m) at (25:2);
coordinate (n) at (-95:2);
coordinate (p) at (145:2);
coordinate (o) at (0,0);
fill[black] (a) circle (2pt) (b) circle (2pt) (m) circle (2pt) (n) circle (2pt) (p) circle (2pt) (2,0) circle (2pt);
draw (a) node[above right] {$z=|z|e^{itheta}$};
draw (b) node[below] {$|z|$};
draw (2,0) node[below] {$|z|^{1/3}$};
draw (m) node[right] {$|z|^{1/3}e^{itheta/3}$};
draw (n) node[below] {$|z|^{1/3}e^{i(theta+4pi)/3}$};
draw (p) node[above] {$|z|^{1/3}e^{i(theta+2pi)/3}$};
draw (.1,1.5)--(0,1.5) node[left] {$i$};
draw (1.5,.1)--(1.5,0) node[below] {$1$};
draw (0,0)--(a) (0,0)--(m) (0,0)--(n) (0,0)--(p);
draw[dashed] (m)--(n)--(p)--cycle;
pic[draw,dashed,thick,"$theta$",angle radius=0.8cm,angle eccentricity=1.3] {angle=b--o--a};
end{tikzpicture}
end{document}


gives this output





Seeing that it is a bit difficult to read some nodes (like the |z|1/3ei (θ + 2 π)/3 one), I redefine the inner sep and set the fill color of the nodes. Eventually I get



documentclass[tikz]{standalone}
usetikzlibrary{quotes,angles,positioning}
begin{document}
begin{tikzpicture}
begin{scope}[every node/.style={fill=white,inner sep=2pt}]
draw (0,-4)--(0,4) node[above] {$Im$} (-4,0)--(4,0) node[right] {$Re$};
draw[dashed] (0,0) circle (3) circle (2);
coordinate (a) at (80:3);
coordinate (b) at (3,0);
coordinate (m) at (80/3:2);
coordinate (n) at ({80/3-120}:2);
coordinate (p) at ({80/3+120}:2);
coordinate (o) at (0,0);
draw (a) node[above right] {$z=|z|e^{itheta}$};
draw (b) node[below right] {$|z|$};
draw (2,0) node[below left=0cm and -2em] {$|z|^{1/3}$};
draw (m) node[right] {$|z|^{1/3}e^{itheta/3}$};
draw (n) node[below] {$|z|^{1/3}e^{i(theta+4pi)/3}$};
draw (p) node[above] {$|z|^{1/3}e^{i(theta+2pi)/3}$};
draw (.1,1.5)--(0,1.5) node[left] {$i$};
draw (1.5,.1)--(1.5,0) node[below] {$1$};
draw (0,0)--(a) (0,0)--(m) (0,0)--(n) (0,0)--(p);
draw[dashed] (m)--(n)--(p)--cycle;
end{scope}
pic[draw,dashed,thick,"$theta$",angle radius=0.8cm,angle eccentricity=1.3] {angle=b--o--a};
fill[black] (a) circle (2pt) (b) circle (2pt) (m) circle (2pt) (n) circle (2pt) (p) circle (2pt) (2,0) circle (2pt);
end{tikzpicture}
end{document}




The separation of the nodes and the paths are now quite good IMHO, except some cases where the separation is over-made:







A solution to it is to change the default rectangle node shape





to something like this





Sorry, I am not good at drawing, especially drawing with a computer mouse.



In other word, I think I have to create a new TikZ node shape which depends on the maximum and the minimum "y-coordinates" of all characters.



It is way too complicated to me, and I haven't found a hint on this.



Can you help me? Any help is much appreciated.
