Answer 1

No usaría negrita en el encabezado: \bm{\beta}y \betason dos entidades matemáticas diferentes.

Además, la primera columna no tiene por qué estar en negrita. La tercera columna, que tiene un solo número, puede ser simplemente c, con \numel número; Si se trata sólo de una versión íntegra, debe poner entre llaves las entradas no numéricas.

Esta debería ser tu tabla y ser compilable:

\documentclass[a4paper,12pt]{report}
\usepackage{multirow}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{amsmath}

\begin{document}
\begin{table}[!htbp]
\centering
\begin{tabular}{>{\bfseries}c % I think centred column looks better here
               S[table-format=-1.2(2)] 
                S[table-format=1.1e1] } 
\toprule 
  Approach & $\boldsymbol{\beta}$ & $\boldsymbol{\chi^{2}}$ \\
   \midrule
1   &  -0.61(17)        & {Inf.} \\
2   &  -0.60(17)        & {Inf.} \\
3   &  -0.59(18)        & 3e6 \\ 
3   &  -0.59(18)        & 3.0e6 \\ % for comparison
4   &  -0.56(20)        & {Inf.} \\
\bottomrule
